This package provides functions for computing the density and the distribution function of multivariate normal and multivariate Student's t variates and for generating random vectors sampled from these distributions.
Probabilities are computed via a non-Monte Carlo method. Different routines
are used in the three cases
d=1, d=2, d>2, if
d denotes the
number of dimensions.
