| 摘 要： | 本文讨论了检验样本是来自一个正态总体还是两个未知均值和方差的正态的混合分布，采用对数极大似然比的检验，如果不加限制，Ｈａｒｔｉｎｇａｎｍ曾指出不是寻找的、Ｘ＾２分布，我们在混合的中了一点后得到了其极限分布产工给出了分位点数值表。

| Abstract: | The limit distribution of the log maximnm likelihood ratio statistic for finite mixture mod-els is not the usual chisqure (Hartigan 1985). We have considered the limit distribution of the restricted log maximum likehood ratio for mixture models of two distributions with single un-known parameter [2]. But it does not contain mixture models of two useful normal distribution with unknown mean and variance, it has another limit distribution. In this paper, we give this limit distribution and its tables of values. |
