We use the EM algorithm to derive recursive expressions for maximum likelihood location and scale estimators for Tukey's corner distributions, in particular the one-wild. This now enables optimal estimation for the triefficiency criterion used to appraise robust estimators. The effect of...

This paper adds the technique of chain completion to the setting of [MCB94]. We develop the theory of chain completion of a domain and show how this completion relates to metric and ideal completion. Especially we study consistency results for denotational semantics on , and

This article presents a new area of application for Automatic Differentiation (AD): Computing parametric sensitivities for optimisation problems. For an optimisation problem containing parameters which are not among the optimisation variables, the term parametric sensitivity refers to the...

It is shown that Electromagnetism creates geometry different from Riemannian geometry. General geometry including Riemannian geometry as a special case is constructed. It is proven that the most simplest special case of General Geometry is geometry underlying Electromagnetism. Action for...

Clustering nouns can be useful in construction of a set of synonyms for word sense disambiguation, to perform query expansion in a QA system [10], to build ontology from a text, in data mining, etc., especially for languages different to English for which doesn't exist such hierarchy as WordNet...

In dealing with parametric nonlinear mixed effects models, intensive numerical integration often makes exact maximum likelihood estimation impractical given the current computing capacity. Algorithms based on linearization, such as the first order method and the conditional first order method,...
