A Note on the Estimation of the Multinomial Logit Model

The multinomial logit model with random eeects is often used in modeling correlated nominal polytomous data. Given that there is no standard software of tting it, we advocate using either a Poisson log-linear model or a Poisson nonlinear model, both with random eeects. Their implementations can be carried out easily by many existing commercial statistical packages including SAS. A brand choice data set is used to illustrate the proposed methods.).
