BAYESIAN INFERENCE FOR THE HALF-NORMAL AND HALF-T DISTRIBUTIONS [PDF]
In this article we consider approaches to Bayesian inference for the half-normal and half-t distributions. We show that a generalized version of the normal-gamma distribution is conjugate to the half-normal likelihood and give the moments of this new ...

Using the skew-t copula to model bivariate rainfall distribution [PDF]
, 2010 We simulate monthly rainfall at two sites in the Murray--Darling Basin. In order to construct a suitable joint distribution, we model the individual totals using appropriate gamma distributions and use a multivariate skew-t distribution to construct an ...
