Re: [Gretl-users] Exact collinearity and modprint

Is there a way to retrieve the list of regressors dropped by gretl or
the list of regressors eventually used in the regression?
Ignacio has answered the question in your second paragraph: you can
use the $xlist accessor.
But I'm a bit puzzled as to why you'd want to use "modprint" after
running a regression via a gretl command. The intention with
"modprint" is that you're printing the results of some operation
which estimates a model, but is not a built-in gretl modelling
command.
