Outline of Final Research Achievements 
We derived the following conclusions (i)(iv) for multiple comparison procedures in multisample models. (i) Suppose that the simple order restriction of means is satisfied under the underlying normal distribution. Then, for the differences among mean responses, a closed testing procedure is superior to the single step Hayter's test (Hayter (1990)). To compute the upper percentiles of the distributions of statistics, the sinc method described in Lund and Bowers (1992) and Stenger (1993) is utilized. (ii) Suppose that the underlying distribution is a normal distribution function with unequal variances. Then, for the differences among mean responses, Shiraishi and Hayakawa (2015) propose a closed testing procedure superior to the single step GamesHowell test. (iii) Suppose that the underlying distribution is unknown. Then nonparametric multiple comparison procedures are discussed. (iv) Under Bernoulli distribution, the theory of multiple comparison procedures are constructed.
