   Kurtosis
   Is the statistic which describes the degree of peakedness or flatness of a probability distribution relative to the benchmark normal distribution. See Leptokurtic (Leptokurtosis) and Platykurtic (Platykurtosis).

   Kurtosis
   An expression of the so-called 'fourth moment'. A tendency for a distribution to form a sharp narrow peak in the center (or, when negative, a broad flat plateau). It is a unitless parameter. If the value is positive it indicates that the distribution of the signal has longer tails than the Gaussian distribution (a spikier signal). If the value is n...

   Kurtosis
   Definition (undergraduate level) For a given frequency function, the kurtosis is a measure of how sharply the function peaks around its mode.<br /> The coefficient of kurtosis is a quantitative measure of the kurtosis; it is γ 2 = μ 4 μ 2 2 - 3 , where μ i is the i th moment of the function about its mean.

   kurtosis
   An attribute of a distribution, describing 'peakedness'. Kurtosis is calculated as E[(x-mu)⁴]/s⁴ where mu is the mean and s is the standard deviation. Source: Hogg and Craig, p 57 Contexts: econometrics; statistics

   Kurtosis
   In probability theory and statistics, `kurtosis` is a measure of the `peakedness` of the probability distribution of a real-valued random variable. Higher kurtosis means more of the variance is due to infrequent extreme deviations, as opposed to frequent modestly-sized deviations.
