3.1. Data description

Statistics on Business enterprise R&D (BERD) measure research and experimental development (R&D) performed in the business enterprise sector, i.e. R&D expenditure and R&D personnel. In line with this objective the target population for the national R&D survey of the business enterprise sector consist of all R&D performing enterprises (including all R&D performers – occasional and continuous, known and unknown - in all branches and size classes) belonging to this sector. The “enterprise” is defined in Council Regulation (EEC) No 1993/696 of 15 March 1993. The results are related to the population of all R&D performing enterprises classified in Sections A to U of the common statistical classification of economic activities as established by Regulation (EC) No 1893/2006 of the European Parliament and of the Council (NACE Rev.2).

 

The main concepts and definitions used for the production of R&D statistics are given by OECD (2015), Frascati Manual 2015: Guidelines for Collecting and Reporting Data on Research and Experimental Development, The Measurement of Scientific, Technological and Innovation Activities, which is the internationally recognised standard methodology for collecting R&D statistics and by Eurostat’s European Business Statistics Methodological Manual on R&D Statistics. (EBS Methodological Manual on R&D Statistics).

 

Since the beginning of 2021, the collection of R&D statistics is based on Commission Implementing Regulation (EU) No 2020/1197 of 30 July 2020. The Regulation sets the framework for the collection of R&D statistics and specifies the main variables of interest and their breakdowns at predefined level of detail. Statistics on science, technology and innovation were collected until the end of 2020 based on Commission Implementing  Regulation (EU) No 2012/995 concerning the production and development of Community statistics on science and technology.

3.6. Statistical population

See below.

3.6.1. National target population

The objective of the European R&D statistics is to cover all intramural R&D activities. In line with this objective the target population for the national R&D survey of the Business Enterprise Sector should consist of all R&D performing enterprises (including all R&D performers – occasional and continuous, known and unknown - in all branches and size classes) belonging to this sector. In practice however, countries in their R&D surveys might exclude some enterprises for which R&D activities are deemed to be non-existent or negligible, in order to limit the response burden or due to budgetary constraints.

 

  Target population when sample/census survey is used for collection of raw data Target population when administrative data or pre-compiled statistics are used
Definition of the national target population  The target population for R&D is currently the same as the one used for the CIS survey, but of course, only the R&D performers are taken into account.  
Estimation of the target population size  Around 2000 enterprises.  
Size cut-off point  Enterprises with less than 10 employees are not covered.  
Size classes covered (and if different for some industries/services) - 10 - 49
- 50 - 249
- 250+
 
NACE/ISIC classes covered  

- Manufacturing (NACE Rev.2 10-33);
- Electricity, gas, steam and air conditioning supply (NACE Rev.2 35);
- Water supply, sewerage, waste management and remediation activities (NACE Rev.2 36-39);
- Wholesale trade (NACE Rev.2 46); 
- Transportation and storage (NACE Rev.2 49-53);
- Information and communication (NACE Rev.2 58-63);
- Financial and Insurance activities (NACE Rev.2 64-66);
- Architectural and engineering activities; technical testing and analysis (NACE Rev.2 71);
- Scientific research and development (NACE Rev.2 72);

- Advertising and market research (NACE Rev.2. 73).
 
3.6.2. Frame population – Description

The target population is the population for which inferences are made. The frame (or frames, as sometimes several frames are used) is a device that permits access to population units. The frame population is the set of population units which can be accessed through the frame and the survey data really refer to this population.

 

Method used to define the frame population  For this reference period, the CIS population is used as a frame.
Methods and data sources used for identifying a unit as known or supposed R&D performer

Important R&D performers identified in previous surveys are included in the sample.

Starting with the 2012 CIS-R&D survey, we also use administrative data to include all recipients of R&D subsidies for the given period in the sample.

Frequency and the methods applied for inclusion R&D performers not known and not supposed to perform R&D  All respondents to the CIS-R&D (even not known performers) survey are also required to answer if they performed R&D and complete the R&D part if this is the case.
Number of “new”1) R&D enterprises that have been identified and included in the target population  N/A
Systematic exclusion of units from the process of updating the target population  Yes. Public research centres are excluded from BES since they are included in GOV statistics. Enterprises with less than 10 persons employed are currently not covered.
Estimation of the frame population  Around 2000 enterprises.

11. Quality management Top
11.1. Quality assurance

Frascati manual provides guidelines for collecting and reporting data on research and experimental development, providing internationally accepted definitions of R&D and classifications of its component activities.

11.2. Quality management - assessment

A weak point in the national methodology is that some economic activities, as well as micro-enterprises, are currently not surveyed, and based on the hypothesis that R&D in these activities/size-classes is negligible.


To assess the need for additional survey coverage / verify the hypothesis, a question on R&D has been included in the SBS survey starting in the reference year 2010. Since the SBS sample covers around 3000 units, including a rotating sample of micro-enterprises, this question will help to identify unknown R&D performers. This will allow us to define the target population more accurately and to adjust the sample of future R&D surveys if necessary.

We also started including additional data sources in order to identify R&D performers (e.g. data on R&D subsidies).

13. Accuracy Top
13.1. Accuracy - overall

Accuracy in the statistical sense denotes the closeness of computations or estimates to the exact or true values. Statistics are not equal with the true values because of variability (the statistics change from implementation to implementation of the survey due to random effects) and bias (the average of the possible values of the statistics from implementation to implementation is not equal to the true value due to systematic effects).

 

Several types of statistical errors occur during the survey process. The following typology of errors has been adopted:

1. Sampling errors. These only affect sample surveys. They are due to the fact that only a subset of the population, usually randomly selected, is enumerated.

2. Non-sampling errors. Non-sampling errors affect sample surveys and complete enumerations alike and comprise:

a) Coverage errors,

b) Measurement errors,

c) Non response errors and

d) Processing errors.

 

Model assumption errors should be treated under the heading of the respective error they are trying to reduce.

13.1.1. Accuracy - Overall by 'Types of Error'
  Sampling errors Non-sampling errors1) Model-assumption Errors1) Perceived direction of the error2)
Coverage errors Measurement errors Processing errors Non response errors
Total intramural R&D expenditure  4  1  2  5  3    +/-
Total R&D personnel in FTE    +/-
Researchers in FTE    +/-

1)  Ranking of the type(s) of errors that result in over/under-estimation, from the most important source of error (1) to the least important source of error (5). In the event that errors of a particular type do not exist, is used the sign ‘-‘.

2)  The perceived direction of the ‘overall’ error using the signs “+” for over estimation, “-” for under estimation and “+/-” when assumption of the direction of the error cannot be made for R&D.

Full data consistency with reference to totals and relationships between variables in the dataset sent to Eurostat.  

2) 'Good' = In the event that at least one out of the three criteria above described would not be fully met.

3) 'Satisfactory' = In the event that the average rate of response would be lower than 60% even by meeting the two remaining criteria.

4) 'Poor' = In the event that the average rate of response would be lower than 60% and at least one of the two remaining criteria would not be met.

5) 'Very Poor' = If all the three criteria are not met.

13.2. Sampling error

That part of the difference between a population value and an estimate thereof, derived from a random sample, which is due to the fact that only a subset of the population is enumerated.

13.2.1. Sampling error - indicators

The main indicator used to measure sampling errors is the coefficient of variation (CV).
Definition of coefficient of variation:

13.3. Non-sampling error

Non-sampling errors occur in all phases of a survey. They add to the sampling errors (if present) and contribute to decreasing overall accuracy. It is important to assess their relative weight in the total error and devote appropriate resources for their control and assessment.

13.3.1. Coverage error

Coverage errors (or frame errors) are due to divergences between the target population and the frame population. The frame population is the set of target population members that has a chance to be selected into the survey sample. It is a listing of all items in the population from which the sample is drawn that contains contact details as well as sufficient information to perform stratification and sampling.

 

a)       Description/assessment of coverage errors:

 

Only 0.6% of the initial gross sample selected turned out to be non-eligible enterprises that had to be dropped.

 

b)       Measures taken to reduce their effect:

 Multiple sources of information are used to update the register of known or assumed R&D performers.  As they are the major contributors to the final R&D numbers, we feel confident in our coverage of the target population.  

In addition, we evaluate our sources by detecting newcomers in each survey wave.

 

13.3.1.1. Over-coverage - rate

Magnitude of error (%) = (Observed Value-True Value)/ True Value (%)

13.3.1.3. Frame misclassification rate

Misclassification rate measures the percentage of enterprises that changed stratum between the time the frame was last updated and the time the survey was carried out. It is defined as the number of enterprises that changed stratum divided by the number of enterprises which belong to the stratum, according to the frame. The rate can be estimated based on the characteristics of the surveyed enterprises.

Number of surveyed enterprises that have changed stratum (after inspection of their characteristics)          
Misclassification rate          
13.3.2. Measurement error

Measurement errors occur during data collection and generate bias by recording values different than the true ones (e.g. difficulty to distinguish intramural from extramural R&D Expenditure). The survey questionnaire used for data collection may have led to the recording of wrong values, or there may be respondent or interviewer bias.

 

a)       Description/assessment of measurement errors:

 Given that the survey unit is normally the enterprise, it is possible that respondents sometimes respond only for parts of the enterprise as defined by the business register

 

b)      Measures taken to reduce their effect:

   Respondents are informed about the scope of the enterprise as defined by the business register, i.e. a list of all the legal units to be included in their response

13.3.3. Non response error

Non-response occurs when a survey failed to collect data on all survey variables from all the population units designated for data collection in a sample or complete enumeration.

There are two elements of non-response:

- Unit non-response, which occurs when no data (or so little as to be unusable) are collected on a designated population unit.

- Item non-response, which occurs when data only on some, but not all survey variables are collected on a designated population unit.

The extent of response (and accordingly of non response) is also measured with response rates.

13.3.3.1. Unit non-response - rate

The main interest is to judge if the response from the target population was satisfying by computing the weighted and un-weighted response rate.
Definition:
Eligible are the sample units which indeed belong to the target population. Frame imperfections always leave the possibility that some sampled units may not belong to the target population. Moreover, when there is no contact with sample units and no other way to establish their eligibility they are characterised as ‘unknown eligibility units’
Definition:
Un-weighted Unit Non- Response Rate = 1 - (Number of units with a response) / (Total number of eligible and unknown eligibility units in the survey) 
Weighted Unit Non- Response Rate = 1 - (Total weighted responding units) / (Total weighted number of eligible / unknown eligibility units in the sample)

14. Timeliness and punctuality Top
14.1. Timeliness

Timeliness and punctuality refer to time and dates, but in a different manner: the timeliness of statistics reflects the length of time between their availability and the event or phenomenon they describe. Punctuality refers to the time lag between the release date of the data and the target date on which they should have been delivered, with reference to dates announced in the official release calendar.

14.1.1. Time lag - first result

Time lag between the end of reference period and the release date of the results:
Indicator: (Release date of provisional/ first results) - (Date of reference for the data)

 

a) End of reference period: T

15.1.2. General issues of comparability

The Luxembourg R&D data collection also takes into account the smaller R&D firms, but not micro-enterprises (1-9 employees). 
Nevertheless, the survey results indicate a concentration of R&D among very few firms: in 2003 for example, about 5% of the R&D firms conduct approximately two-third of the R&D of this sector.

16. Cost and Burden Top

The assessment of costs associated with a statistical product is a rather complicated task since there must exist a mechanism for appointing portions of shared costs (for instance shared IT resources and dissemination channels) and overheads (office space, utility bills etc). The assessment must become detailed and clear enough so that international comparisons among agencies of different structures are feasible.

18.1. Source data

Several separate activities are used for the collection of raw data or pre-compiled administrative data and statistics related to R&D. For simplicity, we call them surveys irrespective of whether they are sample surveys, censuses, collections of administrative data/pre-compiled statistics. This section presents the names of the surveys by sector of performance as well as methodological information for each survey. Depending on the type of survey and sector of performance, only the sections corresponding to that survey and sector are filled in.

18.1.1. Data source – general information
Survey name  Survey on R&D 2021 (starting with the year 2015)
Type of survey  The survey is mandatory; web survey (optional paper questionnaire).
Combination of sample survey and census data  Both methods are used: Large and medium enterprises (> 50 employees and > 250 employees) are always censused, while SMEs are censused only when belonging to small size strata. Additionally, enterprises that received an R&D subsidy for the reference period are also censused.
Combination of dedicated R&D and other survey(s)  In the even years the data are collected using a combined R&D-CIS questionnaire.
    Sub-population A (covered by sampling)  Apart from large enterprises (> 250 employees) and medium enterprises (50+), strata are sampled if strata sizes are sufficiently large.
    Sub-population B (covered by census)  Large enterprises and medium enterprises (> 250 employees and >50 employees) are always censused.
All other strata are only censused if strata sizes are too small.
Variables the survey contributes to  R&D expenditure by type of cost
Types of R&D
R&D personnel (HC and FTE) by function. 
R&D personnel (FTE) by sex
R&D expenditure by source of funds
Survey timetable-most recent implementation  Data are collected between December and April, and checked, cleaned up, attributed and weighted from May to July.
18.1.2. Sample/census survey information
  Stage 1 Stage 2 Stage 3
Sampling unit  Active firms registered with the national business register (STATEC).    
Stratification variables (if any - for sample surveys only)  Size (10-49, 50-249, 250+) and economic activity (nine distinct business sectors), thus dividing the target population into 27 groups.    
Stratification variable classes  NACE and size classes.    
Population size  Target population is 2050 enterprises.    
Planned sample size  Gross sample is 550 (ineligibles are included and are removed post survey).    
Sample selection mechanism (for sample surveys only)  The sampling scheme used is a stratified sample based on an optimal allocation approach. The sample is broken down by the size of the enterprise (10-49, 50-249, 250 or more) and the economic activity.    
Survey frame  The samples were constructed from STATEC’s national register of Luxembourg businesses, according to the status of firms economically active. Establishments were broken down by sector, according to their main activity and their size.    
Sample design  The sampling scheme used is a stratified sample. The sample is broken down by the size of the enterprise (10-49, 50-249, 250 or more) and the economic activity.    
Sample size  499 enterprises    
Survey frame quality  Good.

18.3.1. Data collection overview
Realised sample size (per stratum)  499
Mode of data collection  Online questionnaire with postal invitation.
Incentives used for increasing response  The survey is mandatory, non-respondents receive up to 3 reminders, with the third being a registered letter for enterprises with 50 or more employees as well as recipients of R&D subsidies.
Follow-up of non-respondents  Follow-up emails or phone calls are made to improve response rates. These calls are made to non-respondents and to units providing partial responses.
Replacement of non-respondents (e.g. if proxy interviewing is employed)  Total non-response are treated by weighting.
Response rate (ratio of completed "interviews" over total number of eligible enterprises or enterprises of unknown eligibility)  The unweighted response rate is 97%
Non-response analysis (if applicable -- also see section 18.5. Data compilation - Weighting and Estimation methods)  

To treat non-response, the initial sampling weight is first adjusted using the response rate for each stratum. Strata are defined by crossing the following size classes and NACE groupings.

In order to obtain reliable results for quantitative variables (that are in line with SBS totals) the corrected weights are calibrated using to the number of units, the total turnover and the total employment per stratum as auxiliary information.

18.4. Data validation

Given the complexity of measuring R&D spending, identifying real activities of respondents' R&D needs careful validation, thus avoiding underestimating or overestimate R&D work.

Manual validation is applied to all companies having declared R&D activities. In addition, companies that declared no R&D activities, but for which there is historical information (e.g. previous studies) or administrative (e.g. R&D grants) in relation to R&D are assessed.

Error detection is an integral part of data collection and processing activities. Automated checks are applied to data records during on-line collection in order to identify declaration and entry errors. These checks make it possible to detect potential errors in totals and key ratios that exceed tolerance thresholds, as well as problems with consistency of the data collected (e.g. the total of a variable is not equal to the sum of its parts).

Other checks are used during data processing to detect automatically, to detect errors or inconsistencies that remain after collection.

18.5. Data compilation

See below.

18.5.1. Imputation - rate

Imputation is the method of creating plausible (but artificial) substitute values for all those missing.
Definition:
Imputation rate (for the variable x) % = (Number of imputed records for the variable x) / (Total number of possible records for x)*100

18.5.1.1. Imputation rate (un-weighted) (%) by Size class

18.5.4. Weighting and estimation methods
Weight calculation method A first weight is established in order to adjust for the sampling design and the unit-response rate. The inverse of the sampling fraction (number of enterprises) is used for that purpose.

To treat non-response, the initial sampling weight is first adjusted using the response rate for each stratum. Strata are defined by crossing the following size classes and NACE groupings.

In order to obtain reliable results for quantitative variables (that are in line with SBS totals) the corrected weights are calibrated using to the number of units, the total turnover and the total employment per stratum as auxiliary information.
Data source used for deriving population totals (universe description)  In order to derive the population totals the post-strata are used.
Variables used for weighting  The number of enterprises and the number of employees by strata.
Calibration method and the software used  Calibrate function of the R-package
