The paired Hotelling's test for equal multivariate means expects two groups of multivariate data, marked with a group column. Rows within each group must be consecutive. The first row of the first group is paired with the first row of the second group; the second row is paired with the second, etc.
For n<=16, the program also calculates an exact p value based on the T2 statistic evaluated for all possible permutations.
Missing data supported by column average substitution.
