Abstract : In Monte Carlo simulation of multivariate distributions, it is often helpful to use a general class of distributions which share certain defining characteristics but which allow controlled variation of other characteristics. We show how multivariate kurtosis, as measured by Mardia's coefficient, Beta 2,p, can be controlled across the class of elliptically-contoured distributions. This allows convenient assessment of the effects of kurtosis on test power, robustness, or whatever the Monte Carlo subject of interest. We illustrate the method's utility by showing that common tests for skewness are also very sensitive to kurtosis even in nonskewed distributions.
