A sequential likelihood-ratio strategy for analyzing tumor multiplicity data from animal bioassays is described and illustrated. The likelihood function is composed of a negative binomial component for the number of induced tumors per animal and a Weibull component for the time to observation of suc

Many authors of reliability texts and papers recommend or employ the Weibull-to-exponential transformation for ease of use in testing hypotheses and in constructing confidence intervals and bounds on the Weibull characteristic value. In making this transformation, it is assumed that the Weibull shap
Researchers commonly express scepticism about using observational data to estimate the effect of a treatment on an outcome the treatment is intended to affect. In this paper, we consider using data from the Multicenter AIDS Cohort Study (MACS) to determine whether zidovudine prevents the development
