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. Other choices include γ2, to be similar to the notation for skewness, although sometimes this is instead reserved for the excess kurtosis. WebNov 17, 2024 · Excess kurtosis is a statistical term describing that a probability, or return distribution, has a kurtosis coefficient that is larger than the coefficient associated with a 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". WebThe excess kurtosis usually denoted by γ 2 is γ 2 = β 2 ( Normal) − 3. Care must be taken because sometimes authors write "kurtosis" and they mean "excess kurtosis". – Alecos Papadopoulos Dec 3, 2014 at 0:38 1 Re: My … trade general terms for specific names
