Mixture of gaussian heavy-tailed data
Webdistributions are a class of probability distributions that generalise Gaussian distributions, and which can accommodate heavy tails and skewness. The results show that stable … WebThis article studies a new family of bivariate copulas constructed using the unit-Lomax distortion derived from a transformation of the non-negative Lomax random variable into a variable whose support is the unit interval. Existing copulas play the role of the base copulas that are distorted into new families of copulas with additional parameters, allowing more …

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.
