[Gretl-users] Tramo script

I finally rewrote my Tramo-linearization script to take into account some of the new features introduced by Allin, and trying to make the script usable in both, Linux and Windows. You may find it in the attached files. This script uses Tramo to interpolate missing values and correct for outliers, returning the corrected series to the control of gretl. In the example, the series produced by Tramo are always added the suffix "_a". If Tramo detects some missing values and/or outliers it generates a "linearized" series and so a label "Linearized" is added to de descriptive label of the produced series; if Tramo does not detect missing values or outliers it also produces the series with suffix "_a" but now it is labeled as "Original". You should "allow for shell commands" in gretl preferences to use this script. There are two things that I would add to the gretl "wishes list" (not urgent, Allin, if you think that it is not the time now) with respect to this type of script: 1- If gretl automatically produces an "environment variable" indicating whether it is being executed in Linux/Windows, we could go without the parameter "linux=0/1" used in this script. 2- Another problem with the decimal point: as Tramo uses points, this script only works well if the user unselect "use locale settings as decimal points" in preferences. May be posible to have a "set" variable to force the use of decimal points inside a function? -- Ignacio Díaz-Emparanza Dpto. de Economía Aplicada III (Econometría y Estadística) UPV-EHU
