| 摘 要： | 研究了多个相互独立的二元正态分布相关系数的相等性检验问题。定义了一个新的广义检验变量,给出了检验问题的广义p值。这种方法不依赖于大样本近似,而且可以算出广义上的精确p值,弥补了传统方法不适用于小样本的缺陷。

| Abstract: | For the problem of testing the equality of the correlation coefficients from several independent bivariate normal populations, a new generalized test variable is given and the generalized p-value based on the test variable is derived. This proposed procedure can calculate the exact p-value in the generalized sense and does not depend on large-sample approximations. So it is a better choice for testing the equality of the correlation coefficients when are small. |
