Yes, I suppose it does.
Well, it's looking good already (tried with the latest
snapshot on
Windows), but there's one thing that the bkw.gfn package covers and the
'vif' command doesn't, namely nonlinear models. I got an error trying
out 'vif' after an 'nls' block. In the doc for 'vif' this
limitation
doesn't seem to be mentioned. I guess the VIFs themselves do not make
much sense outside of ols (or do they?), but these days the vif command
also gives you the BKW table, of course.
So perhaps could 'vif' be activated for nonlinear models, and give only
the BKW table?
thanks,
sven
