Multinomial Logit Models, with or without Random Effects or Overdispersion - Martin Elff, Zeppelin Universität, Friedrichshafen

The open-source package 'mclogit' allows to fit multinomial logit models without or with random effects. It supports two main types of models: conditional logit models, which can be used to analyse discrete choices (from potentially varying choice sets), and baseline category logit models, which can be used to analyse polychotomous responses. Both types of models can be extended by (multilevel) random effects or an overdipersion parameter. Estimation of random effects variants of these models is based either on a Laplace or Solomon-Cox approximation.

In the session, the specification of conditional logit models and baseline category logit model is discussed with practical examples. In addition, results of a simulation study are presented, which examines the performance of the approximation in finite samples.
