Hungarian Central Statistical Office is now using JDemetra+ for seasonal adjustment


The Hungarian Central Statistical Office (HCSO) is using JDemetra+ as the new standard software for seasonal adjustment starting from the first publication of seasonally adjusted data in 2017. The software change does not affect the used seasonal adjustment method (TRAMO/SEATS) and the standardised procedure of HCSO for producing seasonally adjusted data.


The change does not influence the applicability, the interpretation and the dissemination of seasonally adjusted data. The software change induces revisions but it does not cause breaks in time series.


JDemetra+ is the officially recommended software for seasonal adjustment of official statistics within the European Statistical System and the European System of Central Banks.


If you have any questions or comments regarding seasonal adjustment or specifically the change to JDemetra+, please contact our experts at szezon@ksh.hu.
