This is defined as μ 4 4/μ 22 2 where μ4 is the fourth central moment about the mean and μ 2 is the second central moment about the mean, i.e., the variance. If a distribution has a high central peak and long tails, than the kurtosis is large.

SpletIn probability theory and statistics, skewness is a measure of the asymmetry of the probability distribution of a real-valued random variable about its mean.

The long tail is the name for a long-known feature of some statistical distributions (such as Zipf, power laws, Pareto distributions and general Lévy distributions).
