It is assumed that each respondent was observed for T response. Y_{it} is the t^{th} response for the i^{th} individual/subject and each response is binary. Each subject has covariate X_{i} (individual characteristic) and covariate Z_{ijt} (characteristic of alternative j). Individual response i that is represented by Y_{i} = (Y_{i1},....,Y_{iT}), Y_{it} is t^{nd} response on i^{th} individual/subject and the response is binary. In order to simplify, one of individual characteristic was and alternative characteristics. We studied effects of correlations using data simulation. Methods of estimations used in this study are Generalized Estimating Equations (GEE) and Maximum Likelihood Estimator (MLE). We generate data and estimate parameters using software R.2.10. From simulation data, we conclude that MLE on mixed logit model is better than GEE. The higher correlation among utility, the higher deviation estimator to parameter.]]>Alpu, O. and H.
