3. Statistical presentation | ||||||||||||
3.1 Data description | ||||||||||||
“Indice dei prezzi alla produzione dei servizi” (Services producer price index – SPPI - or Output price index for services) The index measures quarterly changes in the prices of services provided by enterprises to other enterprises and to persons representing enterprises. This means the SPPI cover what are commonly known as business to business transactions, thus leaving out sales to consumers. It is used as a deflator too. | ||||||||||||

8. Release policy | ||||||||||||
8.1 Release calendar | ||||||||||||
Every year, in December ISTAT publishes a release calendar providing the precise release dates for the coming year. The calendar is distributed to the press and is available free of charge to interested parties. The calendar is also disseminated on ISTAT's Internet website. | ||||||||||||

Press releases: http://www.istat.it/en/archive/services+prices | ||||||||||||
10.2 Dissemination format - Publications | ||||||||||||
| ||||||||||||
10.3 Dissemination format - online database | ||||||||||||
The on-line database I.Stat is open and free, statistics are organised by theme in a two-level hierarchical tree. Data are presented in aggregate form in multidimensional tables; acting on variables, reference periods and the arrangement of heads and sides users can create custom tables and graphs. The system can be searched by keyword, theme and region. | ||||||||||||
10.4 Dissemination format - microdata access | ||||||||||||
Before data dissemination, validated microdata are stored in the repository of the Institute, ARMIDA. The repository ARMIDA (Archive of validated microdata) was established with the main objective of preserving and documenting the data produced by Istat surveys, and has subsequently supported the objective of disseminating data. The data archived in ARMIDA supplies, in fact, the different channels for the dissemination of microdata (for internal use at the Institute through the "Memorandum of access to microdata of ARMIDA" internal users ", for authorities in Sistan, for research files, for standard files, etc.). The micro-data stored in ARMIDA are also used to respond to requests of external users submitted to the Adele laboratory http://www.istat.it/en/information/researchers/analysis-of-individual-data | ||||||||||||

11. Quality management | ||||||||||||
11.1 Quality assurance | ||||||||||||
The quality assurance framework is based on the contents of the document "Quality Guidelines For Statistical Processes" – Istat - December 2012 (http://www.istat.it/en/files/2011/11/QualityGuidelines_EngVers_1.11.pdf). Istat reference framework for quality policies relies on the European Statistics Code of Practice adopted in 2005 and revised in 2011, on Eurostat Quality Definition and on the recommendations of the LEG on Quality. The Data Quality Assessment Framework, developed by the International Monetary Fund, also represents an important reference. Following the principles of the European Statistics Code of Practice, Italy has adopted the Italian Code of Official Statistics in order to promote quality improvements of the statistics produced by the Italian National Statistical System. In accordance with Eurostat Quality Definition, the requirements of statistical products are: -to be relevant with regard to users’ information needs; -to be accurate, that is to provide estimates or indicators that are as reliable as possible; -to timely catch the phenomena to be observed; -to be easily accessible and supported by metadata allowing for a fully understanding of data; -to enable comparisons over time or among different sources. A description of methodology and sources used in preparing statistics is also contained in the Information System for Survey Documentation and Quality Control (Siqual) (http://siqual.istat.it/SIQual/lang.do?language=UK). | ||||||||||||
11.2 Quality management - assessment | ||||||||||||
SPPIs meet the quality criteria of relevance, accuracy, timeliness and punctuality, coherence and accessibility. They are computed according to the recommendations of the “Methodological guide for developing producer price indices for services” (OECD/Eurostat) and the “Produce Price Index Manual: Theory and Practice” as well. | ||||||||||||
12. Relevance | ||||||||||||
12.1 Relevance - User Needs | ||||||||||||
The main users are: Eurostat (STS Regulation); National central bank; International organizations; Internal users (especially National Accounts team); Trade unions; Media; Researchers and students; Enterprises. | ||||||||||||
12.2 Relevance - User Satisfaction | ||||||||||||
Not available | ||||||||||||
12.3 Completeness | ||||||||||||
It is partial because among NACE activities included in STS Regulation Groups/Classes H49.4; H50.1; H50.2; H50.1+H50.2 (sum); H51; H51.1; H51.2; H52.1; H52.24; H53; H53.1; H53.2; J61; J61.1; J61.2; N81.2 are covered. On the contrary, indexes for Groups/Classes J62; J63.1; J63.9; M69.1+M69.2+M70.2 (sum); M71; M73; N78; N80 are not produced yet. | ||||||||||||
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. Data check procedure is as well very effective. | ||||||||||||
13.2 Sampling error | ||||||||||||
It is not possible to compute sampling errors because a non-probability sampling method (cut-off with a census above the cut-off) is used | ||||||||||||
13.3 Non-sampling error | ||||||||||||
| ||||||||||||
14. Timeliness and punctuality | ||||||||||||
14.1 Timeliness | ||||||||||||
| ||||||||||||
14.2 Punctuality | ||||||||||||
Releases delivered on time during the year: 4/4 | ||||||||||||
15. Coherence and comparability | ||||||||||||
15.1 Comparability - geographical | ||||||||||||
The comparability of SPPIs between EU countries is ensured by Regulation No 1165/98. | ||||||||||||
15.2 Comparability - over time | ||||||||||||
SPPIs are comparable over time for the entire length of time series. | ||||||||||||
15.3 Coherence - cross domain | ||||||||||||
| ||||||||||||
15.4 Coherence - internal | ||||||||||||
SPPIs are internally coherent. Each SPPI 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 | ||||||||||||
The cost refers to 7 persons working on SPPIs surveys. The statistical burden on reporting units has been reduced adapting the questionnaires according to the information on markets that associations and big companies gave during the meetings organized before surveys started. | ||||||||||||
