|
|||
Eurostat transmissions for this index are carried out on a monthly basis and one month after the end of the reference period. National news releases for the index are also carried out on a monthly basis and according to the national news release calendar. |
|
|||
10.1. Dissemination format - News release | |||
The main dissemination channel for official statistics is the NSO website (http://www.nso.gov.mt). A monthly local news release is published for this indicator. The data are presented at MIG (Main Industrial Grouping) level. |
|||
10.2. Dissemination format - Publications | |||
The short-term statistics only publishes its figures in an annual compendium named Malta in Figures or Trends in Malta. These can be accessed from the NSO website: http://www.nso.gov.mt |
|||
10.3. Dissemination format - online database | |||
The NSO website offers an online statistical database (StatDB) that provides a more in-depth analysis for the more expert statistical user or researcher. The StatDB requires registration as only registered users can extract data from the database. Registration is free-of-charge. Currently, this format is not available for this indicator. |
|||
10.4. Dissemination format - microdata access | |||
In general, index results made available to Eurostat ensure a sufficient degree of representativeness of data. More detailed data than that published locally and internationally are available on request but are subject to the confidentiality clauses. In such cases, data are provided in index form. Micro data are not provided to users. |
|||
10.5. Dissemination format - other | |||
Data are transmitted to Eurostat on a monthly basis and are part of the SDDS system. |
|||
10.6. Documentation on methodology | |||
The main documents used for the production of this index are the following: European Business Statistics Manual, 2021 https://ec.europa.eu/eurostat/en/web/products-manuals-and-guidelines/-/ks-gq-21-001 Producer Price Index manual, 2004 |
|||
10.7. Quality management - documentation | |||
Not available. |
|
|||
11.1. Quality assurance | |||
The NSO quality assurance principles are developed according to the ESS Handbook for Quality Reports (2014). |
|||
11.2. Quality management - assessment | |||
Aspects of quality are divided into several steps. These are specifying needs, designing and building data instruments and collecting, processing, analysing, disseminating, archiving and evaluating data. The main guiding principles in quality management are found in the: European Statistics Code of Practice - https://ec.europa.eu/eurostat/web/quality/european-quality-standards/european-statistics-code-of-practice Quality Assurance Framework of the ESS - http://ec.europa.eu/eurostat/documents/64157/4392716/ESS-QAF-V1-2final.pdf/bbf5970c-1adf-46c8-afc3-58ce177a0646 Overall, the quality of the Industrial Producer Price Index is of good quality and very reliable. |
|
|||
12.1. Relevance - User Needs | |||
The main users of the Industrial Producer Price Index are the following:
|
|||
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 indicator is considered to be of good quality. Sampling error is negligible, non-sampling error is small and the first estimates are not biased. |
|||
13.2. Sampling error | |||
The sampling error is considered to be low, since the sample is a cut-off one and covers over 80% of the industry's turnover. Due to the cutoff technique, an element of sampling bias is present, however this is not currently calculated. |
|||
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 in the industrial producer price index are mainly due to non-response error. However, revisions in the producer price index are negligible and hence, errors are also negligible. Information on data collection errors is not avaiable, however this is considered to be small. Turnover-weighted response rate is over 70%. |
|
|||
14.1. Timeliness | |||
The Industrial Producer Price Index is disseminated one month after the reference period. |
|||
14.2. Punctuality | |||
The NSO is committed to adhere to the timelines established by the STS Regulations and also issues news releases according to its pre-published calendar. All deadlines were 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 STS Regulations and STS Methodological Guidelines. The same concepts are applied to the whole national territory of the Maltese Islands. |
|||
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. There is no break in series in the industrial producer price index. |
|||
15.3. Coherence - cross domain | |||
Data are not compared with any other source. |
|||
15.4. Coherence - internal | |||
Aggregates are consistent with the other components. |
|
|||
Data burden is considered high but no data are available. |
|
|||
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 neews 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 | |||
In practice, routine revisions are done when actual data are received and estimates are replaced. The below Quality Performance Indicators (QPIs) were obtained using annual growth rates for December 2018 as the latest release. To calculate the revisions, the previous 36 monthly periods were used. On average, these are very similiar for each year. Unadjusted annual growth rates:
|
|
|||
18.1. Source data | |||
Data are collected by means of a monthly survey sample of around 80 units. Each unit has one or more products that are monitored every 15th day of the month. |
|||
18.2. Frequency of data collection | |||
Monthly. |
|||
18.3. Data collection | |||
Data is collected by means of a monthly statistical questionnaire sent automatically by the system. Questionnaires are sent and received by e-mail. |
|||
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. The previous period is copied when it comes to industrial producer prices. A Laspeyres type index is used for compilation and the weights are updated every 5 years from the Structural Business Statistics survey. Data is produced in .csv format and converted to .xml format using the SDMX Converter 5.4.4. |
|||
18.6. Adjustment | |||
No adjustments are done. |
|
|||
None. |
