Revision is done due to the questionnaires which are late to index calculation and the errors which are made by the data providers. Revision is done also due to the updating of the base year and changes in statistical methods, concepts, definitions and classifications.
For series; 1. Index values are revised for previous quarter in current quarter. 2. Index values are revised for each quarter in the end of year.
For the seasonal adjusted series; 1. Series are revised during the calculation of each quarter for last three years. 2. In the end of the year due to system and the methodology; the model structure of series, model parameters and outlier structure are revised if there is a change. After this process the series are revised. 3. In seasonal and calendar adjusted data; the model, filters, outliers and calendar variables are re-identified following the publication of the last bulletin of each year. Along the next year, parameters and factors are re-estimated in each bulletin period. The effects of this revision, which is sourced by the re-estimation of seasonality and calendar factors, is reflected on the data of last three years excluding the current year. |
|||
17.2. Data revision - practice | |||

|||
18.6. Adjustment | |||
Seasonal and calendar related effects prevent observing the general tendency of data because of their temporary characteristics. Therefore, identification of seasonal patterns of short term indicators plays crucial role in order to make reliable comparisons between consecutive periods.
