给出了k个协方差矩阵的特征值之间线性趋势的检验方法。这个检验的一个特例是Flury(1986)的特征值相等检验。线性趋势假设似乎比平等假设更适用于数据分析。举例说明了线性趋势假设是可以接受的,而相等假设是被拒绝的。
A test for linear trend among a set of eigenvalues of k covariance matrices is developed. A special case of this test is Flury's (1986) test for the equality of eigenvalues. The linear trend hypothesis appears to be more relevant to data analysis than the equality hypothesis. Examples show how the linear trend hypothesis can be acceptable while the equality hypothesis is rejected.
