High kurtosis distribution
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 ... 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.
