Directions in Robust Statistics and Diagnostics: Part II

This IMA quantity in arithmetic and its purposes instructions IN powerful records AND DIAGNOSTICS is predicated at the lawsuits of the 1st 4 weeks of the six week IMA 1989 summer time software "Robustness, Diagnostics, Computing and pix in Statistics". a major aim of the organizers used to be to attract a large set of statisticians operating in robustness or diagnostics into collaboration at the demanding difficulties in those components, rather at the interface among them.

Bayesian Networks: An Introduction

Bayesian Networks: An creation presents a self-contained creation to the speculation and functions of Bayesian networks, a subject matter of curiosity and significance for statisticians, computing device scientists and people taken with modelling complicated info units. the fabric has been generally verified in lecture room instructing and assumes a simple wisdom of chance, information and arithmetic.

Missing data analysis in practice

Lacking facts research in perform offers useful equipment for studying lacking info in addition to the heuristic reasoning for knowing the theoretical underpinnings. Drawing on his 25 years of expertise learning, instructing, and consulting in quantitative parts, the writer offers either frequentist and Bayesian views.

Statistical Shape Analysis

A completely revised and up-to-date variation of this advent to trendy statistical equipment for form research form research is a crucial device within the many disciplines the place items are in comparison utilizing geometrical positive aspects.  Examples comprise evaluating mind form in schizophrenia; investigating protein molecules in bioinformatics; and describing development of organisms in biology.
