Abstract: Recurrence relations for integrals that involve the density of multivariate Student-t distributions are developed. These recursions allow fast computation of the moments of folded and truncated multivariate normal and Student-t distributions. Besides being numerically efficient, the proposed recursions also allow us to obtain explicit expressions of low order moments of folded and truncated multivariate Student-t distributions. The newly methods are implemented in the new R package MoMtt.
