Dear R users,
the tmvtnorm package, the package for the truncated multivariate normal and
Student-t distribution, has been updated on CRAN.
The major changes in version 1.0-2 (2010-03-04) are:
* The package now provides methods for the truncated multivariate Student-t
distribution, i.e. random number generation, density function, distribution
functions like rtmvt(), dtmvt() und ptmvt() and ptmvt.marginal(). Random number
generation supports both rejection sampling and Gibbs sampling.
* We implemented a thinning technique for the Gibbs sampler in both
rtmvt.gibbs() and rtmvnorm.gibbs(), including additional arguments "thinning",
"start.value" and "burn.in" for controlling the Gibbs sampler.
* We added a parameter "margin=NULL" to dtmvnorm() as an interface/wrapper to
marginal density functions dtmvnorm.marginal() and dtmvnorm.marginal2().
Best regards,
Stefan Wilhelm
