| Outline of Final Research Achievements |
When bivariate log-normal distribution is assumed as the underlying distribution, we proposed a model that fits well. We also show the decomposition theorem of the symmetric model using the proposed model. Furthermore, it was possible to show through simulation that under what conditions the proposed model is good. Other than this, although it can not be called direct research results, a total of seven papers have been accepted and published in peer-reviewed journals in the process of working on the research.

| Academic Significance and Societal Importance of the Research Achievements |
連続型の変数を、いくつかの切断点を設けて離散型の変数に変換し解析を行うことは、医学や経済学など様々な分野で行われているが、潜在分布に焦点を当てた研究はこれまで数少なかった。本研究で得られた成果をそれらの分野のデータに対して適用することで、これまでより詳細な解析が可能となる。
