I have a lot of dummies in a dataset. I include them all during estimation,
but depending on the subsample that I do the estimation on, some are dropped
automatically due to multicollinarity. I would like to quickly test all
dummies that are included in the model, with a for loop over the included
dummies. But how do I get a varlist of the included dummies?

_rmcoll is your friend:

* mpg2, turn2 are copies of mpg and turn
reg price mpg mpg2 turn turn2
local regressors : colnames e(b)
local regressors: subinstr local regressors "_cons" " "
_rmcoll `regressors'
di "`varlist'"
