The Revisions policy as well as the Revisions calendar is available to users on the web portal of the SOSR.
• Policy and calendar of revisions of the SOSR
SOSR distinguishes the following revisions:
from the content point of view
- incorporation of better quality data based on a more complete source, including replacing imputations with collected data
- data modification based on more accurate methodology (in concepts, definitions and classifications) and changes in statistical methods
- performing corrections in source data and calculations
In terms of time, SOSR divides the revisions into
- ordinary revisions are revisions without significant modifications of the methodologies. These are usually more significant data corrections
- extraordinary and major revisions are revisions of definitive data due to significant methodological changes resulting from revision of methodologies, changes in procedures and statistical-mathematical calculation methods or data corrections. An extraordinary revision may result (e.g. by changing the definition) in break in time series data comparability
The policy on vintage database is laid down in the Revision Policy of SOSR.
Vintage database of raw data exists in source database and is not publicly accessible. Data and documents regarding the revision is kept. General information about revision and methodological explanation is published, if relevant.
Coherence of the revision policy is respected for the data released nationally and disseminated to Eurostat.
17.2. Data revision - practice
MAR (Mean Absolute Revision) = MR (Mean Revision) = 0
The main source of information for routine revisions are new or revised data from reporting units.
18.1. Source data
Municipalities provide the regional statistical offices with local aggregated data on building permits on quarterly basis.
Region, district, village
Kind of ownership
18.2. Frequency of data collection
Quarterly data collection
18.3. Data collection
Data collection is organized by specialised regional office of the SOSR in Košice. Data should be submitted on the 12th calendar day following the end of the reference period. Data collection is normally closed 45 calendar days after the end of the reference period.
The electronic data collection of monthly/quarterly data is compulsory since the 1st January 2016 in line with the obligation laid down in the Slovak National Council law No 326/2014 (Digest) amending the Slovak National Council law No 540/2001 on the state statistics.
Formal and logical checks are realised in the process of data entry automatically; (compatible with Validation level 0 and 1), informal checks aim of which is to control the complexity and relations among the variables (compatible with Validation level from 2 to 5). Most of the errors are directly consulted with the reporting units by our regional offices.
18.4. Data validation
The data entry, data completeness and statistical control are organised by specialised regional offices of the SO SR.
It has been distinguished between two levels of checking:
- formal checks, which are realised in the process of data entry automatically; (compatible with Validation level 0 and 1)
- informal checks aim of which is to control the complexity and relations among the variables (compatible with Validation level from 2 to 5)
According to the importance there are classified 2 basic types of informal checks:
I – informative check- this check gives the additional information, which is important for the following process of corrections. It informs also about some inconsistencies in the state of fulfilment of the questionnaire, about item non-response, exceeding stated limits etc.
Z – check of great importance - it is mostly check indicating the exact error and it must be always corrected or explained.
Most of the errors are directly consulted with the reporting units by our regional offices.
18.5. Data compilation
Variables Building permits: number of dwellings and Building permits: square metres of useful floor area are compiled on the base of issued permits. Basic data is available at 6-digit level of CPA and consequently aggregated to the required levels of CPA. For national purposes the aggregated data in the breakdown by ownership and region district are accessible.
18.6. Adjustment
SOSR uses JDemetra+, version 2.2, using TRAMO-SEATS method. As refresh from period to period we use partial concurrent adjustment + Last outliers. Concurrent adjustment is done once a year.
SOSR usually uses predefined models, but this can be changed if we can not find seasonality correctly. In this case we communicate with our colleague responsible for seasonal adjustment at our NSI.
For details on adjustments of the particular variables please see the annexes.
