R announce - Nov 2000 - mvtnorm

Announcement: mvtnorm

	Multivariate Normal and T Distribution

mvtnorm implements two R functions for the computation of the multivariate t
and normal distribution: 

pmvt: 	Computes the the distribution function of the multivariate t
	distribution  for arbitary limits, degrees of freedom and
	correlation matrices  based on algorithms by Genz and Bretz. 

pmvnorm: Computes the distribution function of the multivariate normal 
	distribution for arbitary limits and correlation matrices  based
	on algorithms by Genz and Bretz.


mvtnorm is currently available in CRAN's devel section.

Hello.

I have a small question.  For computing normal CDF you are using 
"mvtdst" wouldn't be use of "mvnpack" be more efficient?

Thanks.
