Abstract

A 2022 paper arXiv:2009.10305v4 introduced the notion of true positive and negative skewness for continuous random variables via Fr\'echet pp-means. In this work, we find novel criteria for true skewness, establish true skewness for the Weibull, L\'evy, skew-normal, and chi-squared distributions, and discuss the extension of true skewness to discrete and multivariate settings. Furthermore, some relevant properties of the pp-means of random variables are established.
