We consider two measures of right/left/overall kurtosis which are based on a recent interpretation of kurtosis as inequality at either side of the median. We derive the symmetric influence functions of these measures and discuss their sampling properties by a simulation-based approach. Bootstrap confidence intervals are constructed for small and medium sample sizes. Compared to the standardized fourth moment coefficient (conventional kurtosis), the two measures are shown to provide both a more reliable and a more sophisticated picture of the kurtosis risk embedded in a dataset.

Abstract

We consider two measures of right/left/overall kurtosis which are based on a recent interpretation of kurtosis as inequality at either side of the median. We derive the symmetric influence functions of these measures and discuss their sampling properties by a simulation-based approach. Bootstrap confidence intervals are constructed for small and medium sample sizes. Compared to the standardized fourth moment coefficient (conventional kurtosis), the two measures are shown to provide both a more reliable and a more sophisticated picture of the kurtosis risk embedded in a dataset.
