Abstract
We study the blocks of interpoint distances, their distributions, correlations,
independence and the homogeneity of their total variances. We discuss the exact
and asymptotic distribution of the interpoint distances and their average under three
models and provide connections between the correlation of interpoint distances with
their vector correlation and test of sphericity. We discuss testing independence of the
blocks based on the correlation of block interpoint distances. A homogeneity test of the
total variances in each block and a simultaneous plot to visualize their relative ordering
are presented.
