I am looking for a parametric (ideally 4 parameters) distribution with which I can model high moments like skewness and kurtosis. I’ve found some references in a topic area Approximate Bayesian … The kurtosis is the fourth standardized moment, defined as where μ4 is the fourth central moment and σ is the standard deviation. Several letters are used in the literature to denote the kurtosis. A very common choice is κ, which is fine as long as it is clear that it does not refer to a cumulant. Other choices include γ2, to be similar to the notation for skewness, although sometimes this is instead reserved for the excess kurtosis.
