Could you please

i) define 'replicate', and

ii) cite any licenses to back up this claim, or simply show us what you

    find so confusing.

I suspect that you are misinterpreting this, and that tramo-seats is indeed "simply" closed-source software that you can get re-distributed in binary form (e.g. from the gretl website, see below), but not in source.

A couple of years ago I toyed with both the US Census' X12-ARIMA procedure and its tramo-seats alternative by Maravall et al. Given how atrociously '1960s' the X12-ARIMA interface is, I toyed with building an R frontend given that you get the Fortran code to X12-ARIMA straight from the Census site . But then something else came up and I never pursued this ...

The closest I know to using x12 and/or tramo-seats from somewhat saner and more modern software is via Allin Cottrell's gretl (cf And per my suggestion a few years back, Allin even hacked a 'gretl to R' interface [ via mucking with ~/.Rprofile which isn't pretty but that is another story ... ]

Hope this helps, Dirk
