Kurtosis is the fourth central movement of a distribution. The first three movements are mean, standard deviation, and skewness. It measures the distribution’s peakedness and the thickness of its tails.
Leptokurtosis, or positive excess kurtosis, indicates a distribution that is more peaked at the center and has fatter than normal tails.
Platykurtosis, or negative excess kurtosis, indicates a relatively flatter top and thinner tails.For more information, see all articles on: Uncategorized See also:
