Abstract. Two families of kurtosis measures are defined as K1(b)=E[ab−|z|] and K2(b)=E[a(1−|z|b)] where z denotes the standardized variable and a is a normalizing constant chosen such that the kurtosis is equal to 3 for normal distributions. K2(b) is an extension of Stavig's robust kurtosis. As with Pearson's measure of kurtosis β2=E[z4], both measures are expected values of continuous functions of z that are even, convex or linear and strictly monotonic in ℜ− and in ℜ+. In contrast to β2, our… Expand
