Measures the fatness of the tails of a probability distribution. A fat-tailed distribution has higher-than-normal chances of a big positive or negative realization.
The kurtosis is the fourth standardized moment, defined as where μ4 is the fourth central moment and σ is the standard deviation. Several letters are used in the literature to denote the kurtosis. A very common choice is κ, which is fine as long as it is clear that it does not refer to a cumulant.

WebOct 23, 2024 · Kurtosis is a measure of whether or not a distribution is heavy-tailed or light-tailed relative to a normal distribution. The kurtosis of a normal distribution is 3. If a given distribution has a kurtosis less than 3, it is said to be playkurtic, which means it tends to produce fewer and less extreme outliers than the normal distribution.
WebKurtosis is a statistical measure that quantifies the degree of peakedness of a distribution. It is a measure of how often values in the distribution fall close to the mean, and how often they fall far away from the mean. A distribution with a high kurtosis is said to be "peaked", while a distribution with a low kurtosis is said to be "flat".
