Kurtosis definitions

Kurtosis

In probability theory and statistics, kurtosis (from the Greek word κυρτός, kyrtos or kurtos, meaning curved, arching) is any measure of the `peakedness` of the probability distribution of a real-valued random variable. In a similar way to the concept of skewness, kurtosis is a descriptor of the shape of a probability distribution and, jus.....

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

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...
