? proposed a numerical algorithm for evaluating multivariate normal probabilities. Starting with version 0.9-0 of the mvtnorm package (??), this algorithm is available to the R community. We give a brief introduction to Miwa’s procedure and compare it to a quasi-randomized Monte-Carlo procedure proposed by ?, which has been available through mvtnorm for some years now, both with respect to computing time and accuracy.
