measure of peakedness
1kurtosis — noun A measure of peakedness of a probability distribution, defined as the fourth cumulant divided by the square of the variance of the probability distribution. See Also: leptokurtosis, mesokurtosis, platykurtosis, excess kurtosis, mesokurtic,… …

6Cokurtosis — A statistical measure that calculates the degree of peak of a variable s probability distribution in relation to another variable s peakedness. All other things equal, a higher cokurtosis means that the first variable has a flatter probability… …
7Platykurtosis — A statistical measure that indicates the level of peakedness of a probability distribution. Specifically, platykurtosis describes a distribution that has a negative excess kurtosis and appears flatter than a normal distribution, which has a… …
