Not yet available for the general public, only internally. |
|
|||

|||
12.2. Relevance - User Satisfaction | |||

|||
12.3. Completeness | |||
Compliant with all STS requirements. |
|
|||
13.1. Accuracy - overall | |||
In principle, a cutt-of sample is used in two stages: at enterprise level and product level. But collection difficulties due to transfer prices, unique products, etc. influence this method. Statistical accuracy is inherently more difficult to assess for price indexes than other statistics due to the complex nature of evolution of average price changes and statistical problems in estimating of data that is not covered by the sample (extrapolation). Errors can occur in price collection and editing, or in making quality adjustments to estimate "pure price change". This results in a small sampling error as well as a non-sampling error. |
|||
13.2. Sampling error | |||
Sampling error is difficult to quantify because on both the statistical unit and product level the sampling is based on judgmental rather than probability sampling methods. |
|||
13.3. Non-sampling error | |||
We improve the response rate with reminders via email or telephone. |
|
|||
14.1. Timeliness | |||
Timeliness 3 months after the reference period. Timetable of data collection: reporting units are contacted by websurvey during the first three weeks after the reference period, reminders are sent afterwards. |
|||

Delays are very rare. |
|
|||
15.1. Comparability - geographical | |||
No problem of geographical comparability, the index is estimated at a national level. |
|||
15.2. Comparability - over time | |||
No problem of comparability over time. |
|||
15.3. Coherence - cross domain | |||
Dissemination of information that support statistical cross-checks and provide assurance of reasonableness: Not applicable. Confrontation with other data sets: Not applicable. |
|||
15.4. Coherence - internal | |||
The index is internally coherent. Higher level aggregations are derived from detailed indices according to well-defined procedures. |
