Abstract:

Section I summarizes several methods for obtaining various useful types of models, particularly ones with U-shaped hazard functions. These models include mixed models, composite models, components in series, nonhomogeneous Poisson Processes, polynomial models and models obtained by transformations from other well-known models. Some point estimation and hypothesis testing results are given for linear and quadratic hazard function models in Section 2. In Section 3 point and interval estimation procedures based on the maximum likelihood estimators for the location and scale parameters of the logistic distribution are considered.
