seasonal adjustment of time series

[george brida]

Dear Octavers,

I am very interested with the programs written in Octave or Matlab that perform seasonal adjustment of time series, especially I would like to know is there any Octave program for X-12-ARIMA and Tramo-Seats the well known methods of seasonal adjustment. These two methods are nowadays integrated in the majority of econometric software like Eviews, Stata, SAS, Gretl....

Thanks in advance
