WebKurtosis (Ku) is a measure of relative peakedness of a distribution. It is a shape parameter that characterizes the degree of peakedness. A distribution is said to be leptokurtic when the degree of peakedness is greater than 3, it is mesokurtic when the degree of peakedness is equal to 3, and it is platykurtic when the degree of peakedness is less than 3. WebJun 27, 2024 · Kurtosis is measured in comparison to normal distributions. Normal distributions have a kurtosis of 3, so any distribution with a kurtosis of approximately 3 is mesokurtic.
