**04 Moments Skewness & Kurtosis Skewness Probability**

As skewness involves the third moment of the distribution, kurtosis involves the fourth moment. The outliers in a sample, therefore, have even more effect on the kurtosis than they do on the skewness and in a symmetric distribution both tails increase the kurtosis, unlike skewness …... The ratio of the third central moment to the cube of the standard deviation is called Pearson’s moment coefficient of skewness (or the coefficient of skewness) and is denoted by . The skewness in (1) can be expanded to derive a version that can be calculated more easily:

Institute of Mathematical Statistics, University of Tartu, J. Liivi 2, 50409 Tartu, Estonia Received 24 May 2006 Available online 10 March 2008 Abstract In this paper skewness and kurtosis characteristics of a multivariate p-dimensional distribution are introduced. The skewness measure is deﬁned as a p-vector while the kurtosis is characterized by a p p-matrix. The introduced notions are...
