Normal distribution with a long tail
Web13 de fev. de 2014 · Some people are interested in skewness or kurtosis to measure the heaviness of the right tail. At a given coefficient of variation, the lognormal is both more skew and has higher kurtosis than the gamma .**. For example, with skewness, the gamma has a skewness of 2CV while the lognormal is 3CV + CV.

Web3 de mar. de 2013 · For a long-tailed distribution, the tails dive to zero very slowly--and hence one is apt to see probability a long way from the body of the distribution. The classical long-tailed distribution is the Cauchy distribution. In terms of tail-length, the histogram shown above would be characteristic of a "short-tailed" distribution. The "who … green yellow vectorWebIn probability theory and statistics, skewness is a measure of the asymmetry of the probability distribution of a real-valued random variable about its mean. The skewness value can be positive, zero, negative, or undefined.
