Abstract
Higher central moments M h = \(\frac{1}{n}\) · \(\sum\limits^{n}_{i=1}\) (x i − E)h are very useful in statistical analysis: the third moment M3 characterizes asymmetry of the corresponding probability distribution, the fourth moment M4 describes the size of the distribution’s tails, etc. To be more precise, skewness M3/σ3 is used to characterize asymmetry, and kurtosis M4/σ4 – 3 is used to characterize the size of the tails (3 is subtracted so that kurtosis is 0 for the practically frequent case of a normal distribution).
