| Outline of Final Research Achievements |
Meta-analysis is a statistical analysis to obtain stronger evidence by combining statistical results of some studies with the same purpose. In this research, I aimed to develop the methodology of meta-analysis from a unified perspective by considering similar methods to meta-analysis conducted in various research ares as well as medical research, where meta-analysis has been conducted mainly for confirmatory purpose. The main research outcome obtained during the study period includes a method of meta-analysis of regression models for prediction. This method combines regression coefficients by correcting the bias in the case where the sets of covariates (explanatory variables) are different in the studies included in the meta-analysis, and is expected to be applied to many other areas as well as medical research.
