MVt distribution class
Description
Class MVtDistribution
implements multivariate t distributions using
code from package mvtnorm. For details to this implementation confer
to the references given in this package.
Objects from the Class
Objects could in principle be created by calls to new
, but more
frequently you would create them via the generating function
MVtDistribution
.
