The system can be searched by keyword, theme and region. More information available in the User Guide http://dati.istat.it/ModalHelp/Istat/WBOS%20User%20Guide%20%28EN%29.PDF | ||||||||||||

More information about procedures applied for quality management and quality assessment in the document "Quality Guidelines For Statistical Processes" - December 2012 http://www.istat.it/en/files/2011/11/QualityGuidelines_EngVers_1.11.pdf | ||||||||||||
11. Quality management | ||||||||||||
11.1 Quality assurance | ||||||||||||
Essential points of Istat quality policy are: process quality, product quality, documentation, respect for respondents, strengthening of statistical literacy, users' orientation. For more details: http://www.istat.it/en/about-istat/quality | ||||||||||||
11.2 Quality management - assessment | ||||||||||||
In 2010 this survey was submitted to an audit on quality in a testing phase http://www.istat.it/en/tools/data-quality/audit | ||||||||||||
12. Relevance | ||||||||||||
12.1 Relevance - User Needs | ||||||||||||
The main users are: Eurostat (STS Regulation); Internal users (especially National Accounts team); Media; Researchers and students; Enterprises; Trade unions. | ||||||||||||
12.2 Relevance - User Satisfaction | ||||||||||||
Not available. | ||||||||||||
12.3 Completeness | ||||||||||||
Eurostat's requirements in terms of time series are fulfilled. | ||||||||||||
13. Accuracy | ||||||||||||
13.1 Accuracy - overall | ||||||||||||
The samples are designed with the cut-off method and therefore sampling errors cannot be measured. Non-sampling errors are reduced or eliminated in the collection phase both using an electronic questionnaire that helps debugging and aiming at an increase of the response rate of enterprises. | ||||||||||||
13.2 Sampling error | ||||||||||||
It is not possible to compute sampling errors because a non-probability sampling method (cut-off) is used. | ||||||||||||
13.3 Non-sampling error | ||||||||||||
| ||||||||||||
14. Timeliness and punctuality | ||||||||||||
14.1 Timeliness | ||||||||||||
| ||||||||||||
14.2 Punctuality | ||||||||||||
All releases delivered according to the timetable. | ||||||||||||
15. Coherence and comparability | ||||||||||||
15.1 Comparability - geographical | ||||||||||||
Not applicable, only national level. | ||||||||||||
15.2 Comparability - over time | ||||||||||||
Time series are available on I.stat since January 2000 (http://dati.istat.it/Index.aspx?lang=en). | ||||||||||||
15.3 Coherence - cross domain | ||||||||||||
| ||||||||||||
15.4 Coherence - internal | ||||||||||||
PPI is a system of five variables, algebraically coherent; three of them are surveyed (domestic market, non-domestic market euro zone, non-domestic market non euro zone). The other two variables are compiled as weighted arithmetic mean of the surveyed ones. In particular, total non-domestic market is a weighted arithmetic mean of euro and non-euro zone; the overall variable is a weighted mean of domestic market and total non-domestic market. Further, each variable is computed as weighted average mean (Laspeyred type index) of sub-indexes, therefore internal coherence is straightforward. Moreover the coherence is achieved annually updating weights (indexes are annually chain linked). | ||||||||||||
16. Cost and Burden | ||||||||||||
14 persons work at Istat for the unit SCI/E, responsible among others for the producer price index survey. | ||||||||||||
17. Data revision | ||||||||||||
17.1 Data revision - policy | ||||||||||||

18.2 Frequency of data collection | ||||||||||||

18.3 Data collection | ||||||||||||
| ||||||||||||
18.4 Data validation | ||||||||||||
Data validation is carried out on: - Prices by a guided and checked data-entry procedures that allows to eliminate the incompleteness errors that could occur during the recording phases and to identify the outlier prices (filtering method); - Trend of indices by comparison between the percentage change on previous month, the percentage change on corresponding month of previous year and a similar product index. | ||||||||||||
