Pearson Distribution
The Pearson distribution is a flexible, four-parameter distribution that has an arbitrary mean, standard deviation, skewness, and kurtosis.
Generating Data Using Flexible Families of Distributions
The Pearson and Johnson systems are flexible parametric families of distributions that provide good matches for a wide range of data shapes.
