Kurtosis   (English)

Definition (undergraduate level)

For a given frequency function, the kurtosis is a measure of how sharply the function peaks around its mode.
The coefficient of kurtosis is a quantitative measure of the kurtosis; it is γ2 = [(μ4)/(μ2 2 )] − 3 , where μi is the ith moment of the function about its mean.
