[Gretl-devel] vif

Hi, I just answered a gretl-related question about the variance inflation factors on Stackexchange (https://stats.stackexchange.com/questions/298612/why-is-variance-inflatio...). When looking at the 'vif' command basically for the first time ever, my first reaction was "why is this a command"? It would seem more natural to call it with "modtest --vif" or something like that. (Although I admit it wouldn't provide any p-values.) Related, shouldn't there be a scripting way to access the output of vif without doing the calculations manually? cheers, sven
