Abstract
A probabilistic DEDICOM model is proposed for mobility tables. The model attempts to explain observed transition probabilities by a latent mobility table and a set of transition probabilities from latent classes to observed classes. The model captures asymmetry in observed mobility tables by asymmetric latent mobility tables. It may be viewed as a special case of both the latent class model and DEDICOM with special constraints. A maximum penalized likelihood (MPL) method is developed for parameter estimation. The EM algorithm is adapted for the MPL estimation. An example is given to illustrate the proposed method
