In many surveys, missing response is a common problem. As an example, Zahner, Jacobs, Freeman and Trainor analysed data from a study of child psychopathology in the State of Connecticut, USA. In that study, the response variable, psychopathology, was inferred from questions that were addressed...

Parallel to Cox's [JRSS B34 (1972) 187-230] proportional hazards model, generalized logistic models have been discussed by Anderson [Bull. Int. Statist. Inst. 48 (1979) 35-53] and others. The essential assumption is that the two densities ratio has a known parametric form. A nice property of...

The paper considers estimating a parameter "&bgr;" that defines an estimating function "U"("y", "x", "&bgr;") for an outcome variable "y" and its covariate "x" when the outcome is missing in some of the observations. We assume that, in addition to the outcome and the covariate, a surrogate outcome...

In statistical applications, we often encounter a situation where a substantial number of observations takes zero value and at the same time the non-zero observations are highly skewed. We propose empirical likelihood-based non-parametric confidence intervals for the mean parameter which have...

A two-sample changepoint model is proposed to investigate the difference between two treatments or devices. Under our semiparametric approach, no assumptions are made about the underlying distributions of the measurements from the two treatments or devices, but a parametric link is assumed...

This study was conducted to analyze the status of energy use for heating in rural areas and the energy demands required by rural households to maintain temperatures suitable for the residents to live comfortably. In addition, suggestions to improve the thermal comfort of such families are put...
