Parameter measures of skewness
Authors:William G. Nichols  Jean D. Gibbons
Affiliation:The University of Alabama
Abstract:
Several different measures of skewness are commonly used in place of γ1, the third central moment divided by the cube of the standard deviation. The numerical values of these measures are compared in this paper for members of the gamma, lognormal or Weibull family of distributions and shown to vary considerably in most cases even when skewness and kurtosis are moderate.
Keywords:third central moment  Gamma distribution  lognormal distribution  Weibull distribution  nonnegative random variables
