| Outline of Final Research Achievements |
In this research project, I addressed several problems in multivariate data analysis, derived new statistical methods to solve the problems and developed theory on their usefulness and optimality. The performances of the suggested methods were investigated through simulation experiments and data analysis. In particular, I obtained research results for the following five topics: (A) New developments in small area estimation based on linear mixed models and generalized linear mixed models, (B) Benchmark problems in small area estimation, (C) Variable selection in linear mixed models, (D) Use of shrinkage estimation methods in high-dimensional multivariate analysis, and (E)Developments of optimality theory in multivariate statistical inference.
