Description

The skewness of a sample distribution is defined as the ratio of the 3rd central moment and the -th power of the 2nd central moment (the variance) of the samples 3. The skewness can also be expressed by the simple moments:

Equation 1.19. 


where are the -th moment and the mean (first moment) of the samples.
