Monitoring of the quality indicators of statistical processes and their results and self-evaluation of statistical survey managers is regularly carried out in order to identify the areas which need improvement and to promptly eliminate the shortcomings.
11.2. Quality management - assessment
The quality of the statistical results meets the requirements of accuracy, timeliness and punctuality, comparability and consistency.
Quality of the information obtained is analyzed when evaluating the indicators. Results of the calculation are compared with the results of the previous year, arithmetic averages are calculated. Outstanding values of indicators are identified and analyzed.

The same revision policy is applied for the data released nationally and transmitted to Eurostat.
Long-term planned (major) revisions are conducted after amendments in legal acts, due to changes in the base year, methodology and classifications entail revisions. The time series from first quarter 1998 (Industry, Construction) or first quarter 2010 (Trade, Services) are back-casted.
17.2. Data revision - practice
After amendments in legal acts, changes of the base year and classifications, detection of significant errors, revisions of statistical indicators are performed. Users are informed about the results and changes.

Before the results are presented to the users, additional quality control of statistical data at the macrodata level is performed. The results of statistical indicators are compared with the previous and corresponding period of the previous year.
18.5. Data compilation
The estimates are computed using regular stratified random sampling formulae (ratio estimator). The index is calculated in comparison with the quarterly average of 2021 (base year). The process of the preparation of statistical information is described in the surveys methodologies:
The time series of wages and salaries are calendar day adjusted, using the TRAMO/SEATS method in JDemetra +. A direct method is used for this adjustment.
The model is chosen using a detailed analysis module. The logarithm of transformation is tested. Calendar factors are estimated, 2 regressors (working days) and national holiday's calendar are used, leap year is adjusted.
The significance levels, the number of outliers and statistics on residuals (residual normality, residual asymmetry, etc.) are controlled in the data series.
Calendar adjustment models and parameters are fixed for one year and revised once a year when the data of all reporting quarters is available. The horizon revision covers 4 years: the current year and 3 years backwards.
The objective of the indicator - index of the wages and salaries - to show the development and changes of wages and salaries in the enterprises of Industry, Construction, Trade and Services.
