High kurtosis distribution
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. Web22 de out. de 2013 · 2. Excess kurtosis = kurtosis − 3, since the normal distribution has kurtosis = 3 (that is what the "excess" refers to). Also, kurtosis is always positive, so any reference to signs suggests they are saying that a distribution has more kurtosis than the normal. Skew indicates how asymmetrical the distribution is, with more skew indicating ...
