This article summarizes recent advances in the modelling of ordered categorical (ordinal)
response variables. We begin by reviewing some models for ordinal data introduced in the …

The present review reports on the mathematical methods and statistical techniques
presently available for hazard characterisation. The state of the art of mathematical …

Estimating equations have found wide popularity recently in parametric problems, yielding
consistent estimators with asymptotically valid inferences obtained via the sandwich formula …

There is a need to define exposure-response curves for both Cu excess and deficiency to
assist in determining the acceptable range of oral intake. A comprehensive database has …

The sandwich estimator, often known as the robust covariance matrix estimator or the
empirical covariance matrix estimator, has achieved increasing use with the growing …

Threshold estimates and superthreshold behaviors for US-induced lung hemorrhage were
investigated as a function of species (adult mice and rats) and US frequency (2.8 and 5.6 …

Exposure‐response analysis of acute noncancer risks should consider both concentration
(C) and duration (T) of exposure, as well as severity of response. Stratified categorical …

Age-dependent threshold and superthreshold behavior of ultrasound-induced lung
hemorrhage were investigated with 116 2.1/spl plusmn/0.3-kg neonate crossbred pigs …

The US Air Force is developing a model to assist commanders in determining when it is safe
to launch rocket vehicles. The model estimates the possible number and types of adverse …

The objective of this study was to assess the threshold and superthreshold behavior of
ultrasound (US)-induced lung hemorrhage in adult rabbits to gain greater understanding …
