Test for hypothesis specified equality of the vector of means associa with two threadments in the multivariate case and further use is made of generalized D2 and Hotellings T2 – statistic. For these it is assumed that the two treatments are normally distributed and covariance matrices are equals. If the hipothesis HO : U1 = U2 is ejected, simultaneous confidence intervals are presented in order that we can dcide which components are contributing to the rejection of the hipothesis. A number of multivariate population associated with different treadment have mean vectors U1 , U2 , ………. Ut . it is desired to test the hipothesis, HO : U1 =U2 = Ut , that these are all equal. A standard format for summarizing the necessary computations is analysis of variance for multivariate data.
