On asymptotic normality of the hill estimator [PDF]
For iid observations from a common distribution Fwith regularly varying tail , a popular estimator of α is the Hill estimator. Regular variation of the distribution tail is equivalent to weak consistency of the Hill estimator in a manner made precise in Mason (1982) but necessary and sufficient conditions for asymptotic normality of this estimator are ...

Penultimate Approximation for Hill's Estimator [PDF]
We prove that the probability distribution of Hill's estimator can be better approximated by a series of appropriate gamma distributions than by the limiting normal distribution.

Inference about the Tail of a Distribution: Improvementon the Hill Estimator [PDF]
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.

Asymptotic Normality of Hill Estimator for Truncated Data
The problem of estimating the tail index from truncated data is addressed in Chakrabarty and Samorodnitsky (2009). In that paper, a sample based (and hence random) choice of k is suggested, and it is shown that the choice leads to a consistent estimator of the inverse of the tail index.

Normalising Transformation of the Hill Estimator
ABSTRACTWe present a normalising transformation of the Hill estimator to improve the convergence rate in finite‐sample performance. Our proposal for the normalising transformation is based on the higher order asymptotic expansion of the Hill estimator. The transformation is automatic and simple in computation. The resulting transformation theoretically

Smoothing the Hill Estimator [PDF]
For sequences of i.i.d. random variables whose common tail 1 –Fis regularly varying at infinity wtih an unknown index –α< 0, it is well known that the Hill estimator is consistent for α–1and usually asymptotically normally distributed. However, because the Hill estimator is a function ofk = k(n), the number of upper order statistics used and which ...

A class of weighted Hill estimators
In Statistics of Extremes, the estimation of the extreme value index is an essential requirement for further tail inference. In this work, we deal with the estimation of a strictly positive extreme value index from a model with a Pareto-type right tail.

Estimating and comparing microbial diversity in the presence of sequencing errors [PDF]
Estimating and comparing microbial diversity are statistically challenging due to limited sampling and possible sequencing errors for low-frequency counts, producing spurious singletons. The inflated singleton count seriously affects statistical analysis
