The equivalence of two estimators of the fixed-effects logit model

Abstract This note shows that the scale-adjusted maximum likelihood estimator suggested by a result of [ Andersen, 1973 . Conditional inference and models for measuring. Mentalhygiejnisk Forlag, Copenhagen.] is equivalent to the conditional logit estimator of [ Chamberlain, 1980 . Analysis of covariance with qualitative data. Review of Economic Studies 47, 225–238.] for the fixed-effects logit model with two time periods. © 1997 Elsevier Science S.A.
