tmvtnorm: A package for the Truncated Multivariate Normal Distribution

This package contains a number of useful methods for the truncated multivariate normal distribution. It considers random number generation with rejection and Gibbs sampling, computation of marginal densities as well as computation of the mean and covariance of the truncated variables.
