[Gretl-users] Error in function

Hi all, I estimated a VAR model using the standard var-command and want to run a function called varmodtest afterwards. The function simply exploits the "modtest" command and merges different specification test results into a matrix which is passed back. <hansl> function matrix varmodtest (scalar order "Lag length") #Serial correlation modtest order --autocorr --quiet matrix OUTSC = $pvalue' | $test' return OUTSC end function var 2 LRM IBO matrix A = varmodtest(4) <\hansl> But I obtain the error: "Can't do this: no model has been estimated yet Data error *** error in function varmodtest" How can the function grab information from the previous VAR estimation? Thanks in advance! Artur
