The skewness parameter does not directly correspond to the degree of skewness. However, all else being equal, a larger (in magnitude) skewness parameter indicates a higher degree of skewness, and a skewness parameter of zero equates to zero skew.
Mainly called for the side effect of plotting. But also returns a named array with some select quantiles of the posterior for the skewness parameter. Returned invisibly.
