Details
详细信息----------Details----------
Several related tests have been proposed for the evaluation of canonical correlations (including Bartlett's Chi-squared test, which is computed by default within cca). This function employs Rao's statistic (related to Wilks' Lambda) as the basis for an F test of each coefficient (and all others in ascending sequence) against the hypothesis that the associated population correlations are zero.
已经被提出了一些相关的测试评估的典型相关分析(包括Bartlett的卡方检验,它的计算方法是默认情况下,在cca)。此功能采用Rao的统计(Wilks的lambda)相关的人口相关性为零的假设,即对每个系数(和所有其他升序顺序)的F检验的基础。
