SPSS 不提供这个测试,
“Cox and Stuart proposed several versions of a nonparametric trend test that were considered simpler to compute than rank correlations, though admittedly less powerful at detection of trends. These tests were considered useful at the time of publication (1955) because of the computational complexity of rank correlation methods. However, with modern computers and software, rank correlation methods are computationally trivial, and there is no practical bar to their use, so there is no good justification for using less powerful simpler approaches, and these methods are not offered in SPSS (and do not appear to be offered in other major statistical packages such as SAS, Stata or S-Plus)”
