to download a Gauss program that implements the proposed estimator. The
program requires as input first-step estimates of the parameters of the
discrete choice selection equation. Click here
to download a Gauss programthat performs conditional maximum likelihood
for a fixed effects logit model. Both programs can accommodate unbalanced
panels.
