Query: Moments of the doubly truncated selection elliptical distributions with
  emphasis on the unified multivariate skew-$t$ distribution   In this paper, we compute doubly truncated moments for the selection
elliptical (SE) class of distributions, which includes some multivariate
asymmetric versions of well-known elliptical distributions, such as, the
normal, Student's t, slash, among others. We address the moments for doubly
truncated members of this family, establishing neat formulation for high order
moments as well as for its first two moments. We establish sufficient and
necessary conditions for the existence of these truncated moments. Further, we
propose optimized methods able to deal with extreme setting of the parameters,
partitions with almost zero volume or no truncation which are validated with a
brief numerical study. Finally, we present some results useful in interval
censoring models. All results has been particularized to the unified skew-t
(SUT) distribution, a complex multivariate asymmetric heavy-tailed distribution
which includes the extended skew-t (EST), extended skew-normal (ESN), skew-t
(ST) and skew-normal (SN) distributions as particular and limiting cases.
