| Outline of Final Research Achievements |
Multivariate survival time distribution was modeled using copula (a function that connects multidimensional probability distribution and its marginal distributions). Based on this model, we developed a discriminant analysis method of multivariate survival time data.In particular, focusing on the application range to medical data, we developed discriminant analysis methods applicable to actual multivariate survival time data in medical research In data analysis of multivariate survival time, censoring of data and non-multivariate normality are important problems. We proposed a parametric model for censoring patterns. Based on copula modeling of multivariate survival distributions, we developed flexible discriminant analysis methods.
