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 … WebThe Y 1 's are multivariate normally distributed. Paired Hotelling's T-Square test statistic is given by the expression below: T 2 = n Y ¯ ′ S Y − 1 Y ¯. It is a function of sample size n, the sample mean vectors, Y ¯, and the inverse of the variance-covariance matrix S Y. Then we … new innovation evms login
