|||
3.4. Statistical concepts and definitions | |||
The Detailed definitions of each indicator are available in Commission Regulation (EU) No 1503/2006. The SSPI are output price indices for the production of services from domestic producers and show the evolution of prices for the services that are provided to customers which are enterprises, they refer to services that are used as intermediate use (Business to Business-Β2Β). Contract pricing: Actual selling price in long term contracts for repeated delivery, to the same customer. Direct use of prices of repeated services: Actual selling price of relatively uniform services, sold regularly to different customers. Hourly rate: Hourly list prices for various categories of staff or services, depending on expertise, level of education or seniority. Model price: A hypothetical or historically sold service. The price is recalculated every quarter by adjusting the factors in the price calculation. Percentage fee: Actual price of services, as a percentage of a contract, an asset or other products. Realized hourly rate: Actual hourly prices are calculated by dividing quarterly revenue for a given service, by the number of hours an employee has spent on this during that quarter. Unit value: Actual selling price is calculated by dividing quarterly revenue for a given service, by number of units sold. |

||||||||||||||||||||||||
13.1. Accuracy - overall | ||||||||||||||||||||||||
The general system for the measurement and monitoring of performance quality is in place at Statistics Lithuania. The following tools for SPPI quality monitoring and assurance are used:
Statistical presentation: A purposive sampling method is used for the selection of legal units, service groups and representative services. Statistical data on legal units providing services for the previous years are used to ensure that the income of legal units selected for the statistical survey makes up not less than 90 per cent of total income of legal units within the respective economic activity. The income of the legal units questioned in the survey should make up no less than 70–80 per cent of the total income of all the legal units within the respective economic activity. Accuracy: The SPPI time series are calculated based on the 2010 index reference period accurate to ten decimal places. The results are rounded to four decimal places and then published in the Database of Indicators (on the Official Statistics Portal) and provided to Eurostat. Monthly, annual, average annual and other price changes are calculated using the SPPI time series accurate to all decimal places and are published rounded to one decimal place. Impact of sampling errors: Sampling errors are not systematically measured. Sampling errors are not relevant in the scope of the SPPIs. To reach a better response rate in every quarter a missing price in the reference period is estimated using the previous period's data on enterprises or the average price development for similar products/enterprises. Impact of non-sampling errors: For the SPPIs non-sampling errors are not quantified but are considered to be small. Accuracy of the first estimates: No first estimates are made. The results published are final and not revised later. Representativity: |
||||||||||||||||||||||||
13.2. Sampling error | ||||||||||||||||||||||||
Role of sampling: Sampling errors are not calculated for SPPIs because the sample is not based on random sampling. The list of enterprises engaged in price monitoring is reviewed every year. Multiple use of sampling in production: Not applicable. Coverage of the main aggregates: Not applicable. Numeric information: Not applicable. Non-probability and cut-off sampling: Not applicable. Clarity: Not applicable. Non-probability and cut-off sampling: Not applicable. |
||||||||||||||||||||||||
13.3. Non-sampling error | ||||||||||||||||||||||||
In 2022, the SPPI had a 100 % response rate. In order to minimise the impact of errors in the data provided by respondents on SPPI indices, appropriate validation procedures are applied. In case of non-response, missing values are imputed. Estimates are made depending on the sector they belong to. In most cases, the price is estimated using the average change in the rest of prices collected for the same service or the corresponding branch. Coverage errors: Not applicable. Data collection or access errors: The impact of data collection (survey instrument, respondent) on the main estimates is not estimated. Non-response rate, per cent:
Editing, coding and imputation errors: No information on the impact of imputation, editing and coding errors. Modeling errors: The impact of models used in estimation on errors is not estimated. |
|
|||
14.1. Timeliness | |||
SPPIs are released each quarter, at 09:00 a. m. (local time), on the 75th day after the end of the reference quarter. |
|||
14.2. Punctuality | |||
Statistical information is published in accordance with an Official Statistics Calendar. In case of delay, users are notified in advance by indicating the reason and a new date of publication. |
|
|||
15.1. Comparability - geographical | |||
SPPIs by economic activity according to NACE Rev. 2 are comparable across the EU. |
|||
15.2. Comparability - over time | |||
Time series for NACE Rev. 2 are comparable over time. Length of comparable time series: SPPIs are compiled and time series are comparable since I quarter 2007.
|
|||
15.3. Coherence - cross domain | |||
Lithuanian SPPI’s are compared with European SPPI time series. |
|||
15.4. Coherence - internal | |||
SPPIs are internally coherent. Lower-level price indices are aggregated to higher-level price indices according to the Laspeyres' formula, using base weights. Each higher-level price index is calculated as a weighted arithmetic mean of lower-level price indices. |
|
|||
The average time spent by respondents on the filling-in of the statistical questionnaire KA-03 is 56 min., KA-04 – 33 min. In 2021, the costs of the NSI were 6 340 hours per year, burden on respondents was about 6 084 hrs 2 min. per year. To reduce the burden, a web-based questionnaire is mainly used. More information on burden reduction can be found at https://osp.stat.gov.lt/statistines-atskaitomybes-burden reduction. |
|
|||
17.1. Data revision - policy | |||
After amendments in legal acts, detection of significant errors, revisions of statistical indicators are performed. Users are informed about their results and changes immediately. Users are informed about planned revisions in advance through a planned statistical information revision calendar. The revision policy of Statistics Lithuania is provided in the document Description of Procedure for Performance, Analysis and Publication of Revisions of Statistical Information, approved by Order No DĮ-173 of 30 June 2021 of the Director General of Statistics Lithuania. Users are informed about scheduled revisions in advance through the Calendar of Scheduled Revisions of Statistical Indicators. The same revision policy is applied to IPI data released nationally and transmitted to Eurostat. |
|||
17.2. Data revision - practice | |||
The results published are final and not revised later. |
|
|||
18.1. Source data | |||
The main data source is the statistical service producer price survey. The data used to calculate the SPPI are mainly obtained through this statistical survey, covering enterprises providing services to other businesses and employing 5 and more persons. The survey sample is drawn using a purposive sampling method. The selection of enterprises for the survey is performed by the Price Statistic Division. An essential criterion for selection is annual income from services. For each activity, the selection of units is carried out to cover from 70 to 80 per cent of income within this activity. The survey covers about 1 950 enterprises. The sample of reporting units is updated at the end of every year. The sample of products is updated at the end of every year and is verified quarterly, depending on needs. In 2022, on average, approx. 3 034 prices of products were collected in approx. 1 844 enterprises on a quarterly basis. For collecting weights, an annual questionnaire KA-03, for collecting prices – a quarterly questionnaire KA-04 are used. |
|||
18.2. Frequency of data collection | |||
Prices are collected quarterly. |
|||
18.3. Data collection | |||
Statistical data are collected through annual (KA-03) and quarterly (KA-04) statistical questionnaires. Statistical questionnaire – annual questionnaire for the selection of representative services (code KA-03) and quarterly questionnaire on service producer prices (code KA-04) are used for collecting data on prices. Reporting forms: electronic statistical data preparation and transfer system e. Statistika, by email, phone. |
|||
18.4. Data validation | |||
A specialist of a regional Data Preparation Division carries out the primary verification of the data received. The Price Statistics Division carries out the secondary verification and editing as well as validation of the data using a data control program designed for checking statistical price data. Data are compared to the data for the previous periods. Reasons for changes (when changes are ≥ +10 per cent or ≤ –10 per cent) in prices are analysed. Particular attention is paid to quality changes, to prices that do not change for a very long time, to the lowest and the highest prices. Price trends are also checked against those in producer prices. |
|||
18.5. Data compilation | |||
The SPPI is a Laspeyres-type price index. The lowest-level price indices are the ratios of the individual prices of individual representative services in the reference quarter to the prices in IV quarter of the previous year. Individual service price indices are aggregated using weights for the reference period (turnover for weights collected specially from respondents) – to obtain higher‑level indices for service headings (CPA 6- and 5-digit levels) for each respondent. Then, the weights collected from respondents are used to obtain higher-level indices (NACE Rev. 2 4‑digit level) for each respondent. These indices are aggregated to the price indices for each activity at NACE Rev. 2 4-, 3- or 2-digit level using weights for the reference year from transport and services statistics. Qualitative changes are taken into account through the use of an overlap method (prices for old and new services are collected in the same month, and the difference between the two prices is taken as a measure of their quality difference) or an expert estimation method, which is based on information on the percentage price effect of quality difference provided by respondents. In case of a missing price, the previously observed price is carried forward or the missing price is imputed by observing the movement in prices for similar services or a group to which the service belongs. If a service becomes permanently unavailable, an appropriate replacement service is selected with specifications close to the previous variety. In case of liquidation of the enterprise or when no appropriate replacement service can be found, figures for services are imputed until the end of the year, after which the service is abandoned. New representative services and new enterprises are introduced at the beginning of each year. Service producer price index methodology (only in Lithuanian). |
|||
18.6. Adjustment | |||
Quality changes are taken into account through the use of a bridged overlap and expert estimation methods. Statistical data are adjusted if the quality of the new (replacing) representative service considerably differs from that of the former (replaced) one; in such case, the impact of the change in quality on the price change is estimated. To maintain compatibility between the price of the replacing and the replaced product, service quality has to be adjusted: the price of the replaced product in the base period is adjusted by eliminating the impact of the change in quality. Methods applied: bridged overlap; overlap; expert estimation. Small changes in characteristics, which are not believed to influence the price, are ignored, and prices for the old item and its replacement are compared directly. Price indices are neither seasonally nor calendar adjusted. When prices for seasonal items are temporarily absent, the last observed price is carried forward. |
