This study employs the panel threshold model to reexamine the non-monotonic relationship between CEO stock-based compensation and firm earnings across various firm-size conditions. The feasibility of the model is tested using data for US non-financial firms from 1993 to 2005. Our empirical...

We consider the issue of assessing influence of observations in the class of Birnbaum--Saunders nonlinear regression models, which is useful in lifetime data analysis. Our results generalize those in Galea <italic>et al.</italic> [8] which are confined to Birnbaum--Saunders linear regression models. Some...

A new Bayesian measure of evidence is used for model choice within the generalized extreme value family of distributions, given an absolutely continuous posterior distribution on the related parametric space. This criterion allows quantitative measurement of evidence of any sharp hypothesis,...

The standard nonparametric, rank-based approach to the analysis of dependent data from factorial designs is based on an estimated unstructured (UN) variance--covariance matrix, but the large number of variance--covariance terms in many designs can seriously affect test performance. In a...

Cox's widely used semi-parametric proportional hazards (PH) regression model places restrictions on the possible shapes of the hazard function. Models based on the first hitting time (FHT) of a stochastic process are among the alternatives and have the attractive feature of being based on a...

In this paper, we compare three residuals to assess departures from the error assumptions as well as to detect outlying observations in log-Burr XII regression models with censored observations. These residuals can also be used for the log-logistic regression model, which is a special case of...

The problem of inference based on a rounded random sample from the exponential distribution is treated. The main results are given by an explicit expression for the maximum-likelihood estimator, a confidence interval with a guaranteed level of confidence, and a conjugate class of distributions...

This paper considers the three-parameter family of symmetric unimodal circular distributions proposed by Batschelet in [1], an extension of the von Mises distribution containing distributional forms ranging from the highly leptokurtic to the very platykurtic. The family's fundamental properties...

Measurement error and autocorrelation often exist in quality control applications. Both have an adverse effect on the <italic>X¯</italic> chart's performance. To counteract the undesired effect of autocorrelation, we build-up the samples with non-neighbouring items, according to the time they were produced. To...
