Web15 apr. 2014 · You could try a mixture of two distributions, Y ( β) = ( 1 − β) Z + β ⋅ X where Z is a normal distribution and X some contaminating distribution (say a skewed heavy-tailed distribution). Now vary β between 0 and 1 to get your ``morphing''. Examples for X could be stable distributions.
