A Logistic -Moment-Based Analog for the Tukey -, , , and - System of Distributions
Figure 4
Two asymmetric - distributions pdfs and their cdfs. The parameters of skew () and kurtosis () are based on (A.2) in Appendix A. The parameters of -skew () and -kurtosis () are based on (2.32) and (2.33). The distribution in (b) is a local pdf in the range of where (2.7) yields .
