Dear Dr. Morse, SPSS will give Hotelling's Trace, and it has to convert to Hotelling's T^2 as follows: Multiplying Hotelling's ... WebWhen a multivariate test is preferred, the obvious choice is the Hotelling’s \(T^2\) test. Hotelling’s test has the same overall flexibility that the t-test does, in that it can also work on paired data, or even a single dataset, though this example will only cover the two-sample …
