Skewness and kurtosis are statistical quantities that might give a better idea about the shape of a distribution. In this tutorial, we’ll discuss skewness and kurtosis in statistics. Firstly, we’ll discuss the definitions of them together with a more general concept, namely moments. Then, we...

Skewness, Kurtosis, and the Normal Curve偏度,峰度,和正常的曲线.doc,Skewness, Kurtosis, and the Normal Curve( Skewness In everyday language, the terms “skewed” and “askew” are used to refer to something that is out of line or distorted on one side.
32、urtosis, which can fall below -2.0.Sune Karlsson, of the Stockholm School of Economics, has provided me with the following modified example which holds the variance approximately constant, making it quite clear that a higher kurtosis implies that there are more extreme observations (or that...

allow any practical use of the kurtosis statistic. Neither the skewness statistic nor the kurtosis statistic will provide useful estimates for the shape parameters of any probability model. (For more on this question see“Problems With Skewness and Kurtosis, Part 2,”Quality Digest, August 1, ...
