Multivariate Analysis-Inference About Two Vectors of Means.
This paper provides the computational formulas necessary for testing the significance of the difference between mean values of two bivariate normal populations by Hotelling’s T2. The T2 statistic has been presented as a function of the univariate “Student’s” t-ratios and within group correlation coefficient. A numerical example has been worked out to help understand the mechanics of this multivariate test procedure.
