The Super Robustness Maximum Likelihood Location Estimator Exponential Power Distribution p < 1
2012/9/18
We proof that statistically, the maximum likelihood location estimator of exponential power distribution is strict super robust, when p < 1.

A class of unbiased location invariant Hill-type estimators for heavy tailed distributions
Asymptotic normality Location invariant Hilltype heavy tailed index estimator Second order regular variation
2009/9/16
Based on the methods provided in Caeiro and Gomes (2002) and Fraga Alves (2001), a new class of location invariant Hill-type estimators is derived in this paper. Its asymptotic distributional represen...
State Classification for a Class of Interacting Superprocesses with Location Dependent Branching

The spatial structure of a class of superprocesses which arise as limits in distribution of a class of interacting particle systems with location dependent branching is investigated. The criterion of ...
Electrostatic Views of Stein-type Estimation of Location Vectors
Coulomb potential function electrostatics estimating function Green's formula James-Stein estimator James-Stein positive-part estimator Pythagorean relationship
2009/3/10
Stein-type estimation of location vectors is discussed with the aid of the theory of electrostatics. We consider a class of estimating functions and assess the superiority of an estimating equation by...

2009/3/5
For estimating the median θ of a spherically symmetric univariate distribution under squared error loss, when θ is known to be restricted to an interval [−m,m], m known, we derive sufficient con...

Singular Value Decomposition (SVD) is the basic body of many statistical algorithms
and few users question whether SVD is properly handling its job.
SVD aims at evaluating the decomposition that bes...
