Abstract

A number of measures of peakedness, shoulder heaviness and tailedness have been proposed in literature. A Weibull family of distributions has peakedness as well as other characteristics with varying degrees depending on the shape parameter of the distribution.   In this paper we apply Blest’s approach for measuring kurtosis of Weibull distributions and make some remarks on its comparison with Pearson’s measure of kurtosis.
