| 摘 要： | 广义线性模型的应用越来越广，但在实际应用中经常磁 样问题：何时应该拟合均值和离差的联合模型？何时只需拟合单一的均值模型？对此，可用散度参数的相等性检验来作为判断的依据。最后还给出了一个检验的具体例子。

| Abstract: | Generalized linear models have been used widely. However, in applications, it is meet that models used are joint models of mean and dispersion or simple models of mean. The problm is determined by equality test on dispersion parameters. In this paper, we give several statistics of the test and their distributions. Finally, a illustrate is geven. |
