| Outline of Final Research Achievements |
We analyze two problems in a finite mixture model in which two or more distributions are additively mixed. First, the finite mixture model can not be distinguished in a binary variable taking values of 0 or 1. We demonstrate that it can be identified in a simultaneous equation model with a continuous variable following the normal distribution. Second, the finite mixture models can not be tested how many distributions it is composed of. Since the likelihood increases endlessly due to over-identification, we propose a Vuong test using Laplace approximation. In Monte-Carlo simulation, Laplace approximation is preferable.
