摘要
本文利用广义p值的方法,给出了一种检验两个Potthoff-Roy生长曲线模型的参数矩阵相等性的精确检验方法,并通过实例对本文所给方法进行了说明.
The concept of a generalized p-value is applied for testing the hypothesis of the kind H0: C'ξ1M =C'ξ2M in two independent Potthoff-Roy growth curve models under the assumption1 of error matrix variate normality and heteroscedasticity. The test based on the generalized p-value calculates the exact p-value in the generalized sense. A numerical example of dental examination data on pupils is presented to illustrate the approach.
