cork

Measurements of the weight of cork borings taken from the north (N), east (E), south (S), and west (W) directions of 28 trees.
 It is of interest to compare the bark thickness (and hence weight) in the four directions.

Routines to perform estimation and inference under the multivariate
t-distribution <doi:10.1007/s10182-022-00468-2>. Currently, the following methodologies
are implemented: multivariate mean and covariance estimation, hypothesis testing
about equicorrelation and homogeneity of variances, the Wilson-Hilferty transformation,
QQ-plots with envelopes and random variate generation.
