Research Interests
  • Theory of statistical inference under order restrictions
    keyword : order restrictions, statistical inference, hypothesis testing, statistical estimation, multivariate normal distribution
    1990.04Main research theme is the statistical inference under order restrictions. At present I am studying testing homogenety of several multivariate normal mean vectors under an order restriction. The goals of the research are deriving useful method and examining its properties..
