A Multivariate Hill Estimator

We propose a simple and semi-parametric estimator for the tail index of a regular varying elliptical random vector. Since, for univariate random variables, our estimator boils down to the Hill estimator and it inherits the simplicity and asymptotic properties, we name it after Bruce M. Hill. The estimator is based on the distance between an elliptical probability contour and the outer – or exce...

A Society of Hill-climbers

|This paper is concerned with function optimization in binary search spaces. It focuses on how hill-climbers can work together and/or use their past trials in order to speed up the search. A hill-climber is viewed as a set of mutations. The challenge is twofold: one must determine how many bits should be mutated, and which bits should preferably be mutated, or in other words, which climbing dir...

A Hill Sanitarium for Burmah

The British JBurmah Gazette of the 18th March contains some correspondence on a subject of great importance, the selection and adaptation of a site for a hill sanitarium for that province. Experience has placed beyond all doubt the unquestionable advantages to health which judiciously chosen stations on mountain ranges in India offer ; and almost every province in India has now its hill station...

A. V. Hill sticks his neck out.

It is probably unprecedented that an afterdinner speech for the general public is converted into a review article that, 65 years later, is still on an exponential growth curve of citations in the primary scientific literature. But then again, Archibald Vivian Hill was not your average after-dinner speaker. Hill shared a Nobel Prize in 1922 for his discoveries related to muscle heat production a...
