The main guiding principles in quality management are found in the: European Statistics Code of Practice Quality Assurance Framework of the ESS Overall, the quality of the indices is of good quality and reliable. |
|
|||
12.1. Relevance - User Needs | |||
The main users are the following: - Eurostat; - Central Bank of Malta; - Other international organisations. |
|||
12.2. Relevance - User Satisfaction | |||
Not available. |
|||
12.3. Completeness | |||
Data are compliant with relevant European and local regulations and requirements are fully fulfilled. |
|
|||
13.1. Accuracy - overall | |||
The overall accuracy of the indicators is considered to be of good quality. Sampling error and non-sampling error are small and the first estimates are not biased. |
|||
13.2. Sampling error | |||
The number of observations for this indicator is around 600 business units. NACE Division 47- retail trade, constitute the bulk of these observations - around 500, while the other two NACE divisions (45 and 46) constitute the remaining 200 observation units. Altogether, these business units represent around 80% of the population turnover. The majority of the NACE categories (including the detailed breakdowns for NACE 47) are sampled using non probability sampling methods such as the 80% cut off method or the 1% method (all business units that have at least 1% of total turnover). |
|||
13.3. Non-sampling error | |||
Non-sampling errors relate to problems such as under or over coverage, non-response, data-processing and estimation. Non-sampling errors are mainly due to non-response. Hence, the Short-term Business Statistics Unit use the donor technique using Euclidean distance as the main imputation technique. Weighted Response Rate every month exceeds 70%. The weighting variable to calculate the response rate is turnover. |
|
|||
14.1. Timeliness | |||
The index is disseminated 30 days after the end of the reference period. |
|||
14.2. Punctuality | |||
The NSO is committed to adhere to the timeliness established by the European Business Statistics Regulation (EBS) and also issues news releases according to its pre-published calendar. All deadlines are respected during the course of the year. |
|
|||
15.1. Comparability - geographical | |||
To ensure geographical comparability across member states the index is compiled according to the EBS (European Business Statistics) Regulations. Minor methodological deviations may exist due to specific conditions that apply to each Member State. |
|||
15.2. Comparability - over time | |||
The data series has been compiled since the year 2000. The first set of indicators was based on NACE Rev 1. Following 2009, the indicator was published according to the new NACE Rev 2 classification. Furthermore, for every year ending in 0 or 5, new fixed aggregation weights are introduced. |
|||
15.3. Coherence - cross domain | |||
Data are compared to administrative data. |
|||
15.4. Coherence - internal | |||
Aggregates are consistent with the other components. |
|
|||
Data burden is considered high. 120 hours/month are approximately used for the compilation of these indices. From the respondent point of view, about 15mins/month are used to compile the questionnaire. |
|
|||
17.1. Data revision - policy | |||
Revisions are carried according to the European Business Statistics Regulation. Internal procedures are also established. The same revision policy is applied to both data released nationally and that sent to Eurostat. Revision analysis is carried out before every news release published locally or sent to Eurostat and clear explanations are also sought. Detailed explanations at micro data level are also analysed but only used internally for quality information purposes. Generally, this index will have routine minor revisions due to actual data replacing estimates due to non-response. Major revisions may also be done but this will be on an exceptional basis. A revision calendar does not exist. |
|||
17.2. Data revision - practice | |||
Data marked as provisional are revised when actual data are received and imputations are replaced with such data. The calendar adjusted Mean Absolute Revision (MAR) and Mean Revision (MR) are the below: MAR = 0.029 MR = 0.026 |
|
|||
18.1. Source data | |||
Data are based on a sample survey of around 600 units which is refreshed every 5 years. Turnover and employment are the main variables used for sample design. |
|||
18.2. Frequency of data collection | |||
The frequency of data collection is on a monthly basis. |
|||
18.3. Data collection | |||
Data is collected by means of a statistical questionnaire. Questionnaires are sent by post and their collection is done via post, fax, e-mail or online systems. |
|||
18.4. Data validation | |||
Validations of format and file structure checks and intra-dataset checks are checked with the use of in-house excel sheets and access databases. Revisions analysis is also carried out for every data transmission sent to Eurostat using in-house access queries. When data revisions are significantly large, a short explanation is also given to Eurostat. |
|||
18.5. Data compilation | |||
Non-response is treated by micro-estimation to ensure a full response for all surveyed units. A Laspeyres type index is used for compilation and the weights are updated every 5 years from the Structural Business Statistics survey. The current file conversion is GESMES/TS and the plan is to use the SDMX-ML tool in the future. |
|||
18.6. Adjustment | |||
Unadjusted data are transformed into working day and seasonally adjusted data using the JDemetra+ 2.2.2 software. Automatic filter is used and models and parameters are re-estimated every year. There are no seasonal breaks and the direct adjustment is used. Filter length is chosen automatically and residual seasonality is checked. Further information on seasonal adjustment methods are found in the annex. Annexes: SA Retail Trade Metadata MT |
