WebPrecision in the analysis of the tail of a distribution allows to, for example, perform proper risk evaluation in finance, correcting empirical income distributions for various top-income measurement problems, or individuating a proper growth theory in economics or the biological sciences. WebApr 25, 2024 · and attribute the meaning of fat tails as follows, "The statistical form for a power law is the Pareto distribution (PD), which like the Cauchy distribution, has tails so heavy they confer unusual statistical properties and have been given the name fat-tailed distributions. Power laws are scale independent and intrinsically fractal."

WebWe discuss the estimation of the tail index of a heavy-tailed distribution when covariate information is available. The approach followed here is based on the technique of local polynomial maximum likelihood estimation. The generalized Pareto distribution is fitted locally to exceedances over a high specified threshold.
