摘要
国家标准GB80557-87给出了构造Γ分布形状参数的区间估计的方法,但是所得到的区间估计的水平仅近似地等于1-a,并且这个方法仅当形状参数大时适用.本文给出的构造形状参数区间估计的方法,其水平精确地等于1-a,并且关于形状参数没有任何限制。
In National Standard GB80557-87, one method which is applied to the construction of the confidence interval estimation for the shape parameter of distribution is given, but the confidence level of this confidence interval estimation is equal to 1-a approximately, and this method is applied only when shape parameter is great. In this paper, another method is given, and the confidence level of the interval estimation is equal to 1-a exactly, and there is no restriction about the shape parameter when the method is ap-
