Description

The skew normal family is great for modeling skewed gaussian data, and the student t distribution is great for outliers. But if one has both skewed data and outliers, the skewed t-distribution might be quite useful! How practical would it be to implement this in brms? This paper outlines an implementation in an MLE/EM setting, but I'm not quite skilled enough to implement it in Stan myself.
