A method of generating multivariate non-normal random numbers with desired multivariate skewness and kurtosis [PDF]

open access: yesBehavior Research Methods, 2019
In social and behavioral sciences, data are typically not normally distributed, which can invalidate hypothesis testing and lead to unreliable results when being analyzed by methods developed for normal data. The existing methods of generating multivariate non-normal data typically create data according to specific univariate marginal measures such as ...
