Inference about the Tail of a Distribution: Improvementon the Hill Estimator

International Journal of Mathematics and Mathematical Sciences, 2010, vol. 2010, 1-16

Abstract:

The Hill estimator is often used to infer the power behavior in tails of experimental distribution functions. This estimator is known to produce bad results in certain situations which have lead to the so-called Hill horror plots. In this brief note, we propose an improved estimator which is simple and coherent and often provides an efficient remedy in the bad situations, especially when the distribution is decreasing slowly, when the data is restricted by external cuts to lie within a finite domain, or even when the distribution is increasing.
