Pairwise hotelling's tests
WebFeb 6, 2024 · Usually, I would do this using Hotelling's T-square test statistics. The original Hotelling's equation is: T^2 = (nxny/nx+ny) (X-Y)' S^-1 (X-Y) where X and Y are the vector means, S is the pooled covariance matrix, and nx/y are the sample sizes. However, an assumption of the normal Hotelling's test is that the sample covariance matrices are ... 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 …
