Demetra Plus

Demetra+ and JDemetra+ are seasonal adjustment software based on the two leading algorithms in that domain, i.e. TRAMO-SEATS and X-12-ARIMA/X-13-ARIMA-SEATS.

Versions

 * Demetra+
 * JDemetra+, Java based Demetra, aka NbDemetra based on the NetBeans platform.
 * JDemetra 1.4.1 [V]
 * JDemetra 1.5.2 [V]
 * JDemetra 2.0.0 [V], released on 27.02.2015


 * Demetra+ is available as a Virtualised application and also as virtualised Excel "add-ins"; however, main caveat is that it launches several instances of Excel.

Important Note
The Excel plug-in permitting to run Demetra+ directly from Excel is not anymore supported and distributed. JDemetra+ is the new European software for Seasonal Adjustment, recommended by both Eurostat and the ECB, and I would advise you to move to it, as some Eurostat units already did. You could contact Dario Buono from Eurostat for more information. You will not find at the moment a plug-in permitting a direct access to JD+ from Excel but, as Demetra+ was, JD+ is very user-friendly and can easily read Excel files and output csv files.
