| Research Abstract |
Two new methods of two-stage procedure of constructing a confidence region of the mean vector for non-normal populations are suggested. The one is a method using asymptotic expansion of the distribution, and the other is a method using a bootstrap method. We clarified character of each methods including their drawback. We found another bootstrap method to overcome a problem of over estimating the sample size needed in the original Healy' s two-stage method
