WebInformally, we will say that the distribution has a Pareto tail or that the distribution is of the power-law type. Note that the case 1 < α ≤ 2 (or 1 / 2 ≤ γ < 1) entails distributions with infinite variance and finite mean while the case α > 2 (or γ < 1 / 2) entails distributions with finite mean and variance.

WebApr 23, 2024 · Proof From the general formula for the moments, it's straightforward to compute the mean, variance, skewness, and kurtosis. The mean and variance of X are E(X) = a a + b var(X) = ab (a + b)2(a + b + 1) Proof Note that the variance depends on the parameters a and b only through the product ab and the sum a + b. WebThe Lomax distribution is a heavy tailed distribution originally proposed by Lomax (1987), who used it in his analysis of business failure lifetime data.
