JDemetra+ officially recommended as software for the seasonal adjustment of official statistics - European Statistical System (ESS)

The Seasonal Adjustment Steering Group decided (see joint Eurostat ECB letter) at its meeting in December 2014 that JDemetra+ will be recommended, as of 2 February 2015, as software for conducting seasonal adjustment of official statistics within ESS and ESCB.

This decision was based on:

• The assessment that the seasonal adjustment tools within JDemetra+ ("core engines") comprise all applications necessary to conduct seasonal and calendar adjustment of high statistical quality.
• The results of JDemetra+ testing, in particular by the Seasonal Adjustment Centre of Excellence:
  • Large-scale testing
  • Reproducing seasonal adjustment processes
  • Functional testing of JDemetra+ seasonal adjustment tools vis-à-vis the respective TRAMO-SEATS and X-13ARIMA-SEATS applications
• The availability of documentation in form of a JDemetra+ Quick Start and a JDemetra+ User Manual.

The latest version of JDemetra+ is available for downloading here.
