kurtosis |
Definition
Measure of the relative concentration (flatness or peakedness) of data values in the center versus in the tails of a frequency distribution when compared with normal distribution (which has a kurtosis of 3). Distributions having higher kurtosis have fatter tails or more extreme values (a phenomenon called 'leptokurtosis'), and those with lower kurtosis have fatter middles or fewer extreme value (a phenomenon called 'platykurtosis'). From the Greek 'kyrtosis,' convexity.
