[Gretl-devel] Re: basic questions/comments on X13

Now it seems that The JDemetra+ guys have done the crazy thing. From the reference manual: [...] Eurostat took an initiative to create new software [...] The resulting program is called JDemetra+. [...] the most critical innovation is the re-writing of the original FORTRAN codes of X12-ARIMA/X-13ARIMA-SEATS and TRAMO/SEATS in JAVA, following a real object-oriented approach. (taken from https://ec.europa.eu/eurostat/cros/system/files/jdemetra_reference_manual...)

I'm saying "it seems" bacause after navigating the GitHub repo Hélio linked, I can't find any numerical code, and there should be A LOT of that: for example, if JDemetra+ actually implemented X13, it should contain a complete implementation of ARIMA modelling, that I can't find anywhere. Maybe I'm just looking in the wrong place. Oh well.
