WebThe predictive density of the skew normal distribution is k(x;m,s,a) = 2 s f x m s F a x m s . (2) In the following, we use K(x;m,s,a) for the CDF of the skew normal distribution. Note that if a = 0, we have a Gaussian distribution of mean m and variance s2. For m = 0 and s = 1, the Figure2shows the role of a in the skew normal distribution.
