In industries composed of complex equipment, arranged in series or in parallel, a simple failure can mean the shutdown of the production line as a whole, generating huge financial losses and inconvenience. The methodologies for detecting failures and analyzing their effects have great applicability in the industry, for example to improve the performance of products, to optimize their reso…

In studies involving the time until the occurrence of some event of interest (failure) there is a possibility that not always all study subjects experiment the event of interest even if these individuals is observed a very long time. These individuals are said to be cured or immune to the event of interest and, consequently, its population has a proportion of cure. Generally the time unti…
Item Response Theory (IRT) provides sets of models that represent certain characteristics unobservable (latent traits) of individuals (or companies, schools, etc.). This modeling is based on the probability of response of the individual items (or attributes of the latent trait) conditional on latent traits and characteristics of measuring instruments, such as level of difficulty of an ite…
Several authors have preferred modeling survival data in the presence of covariates by the risk function, which is related to its interpretation. It describes how the instantaneous probability of failure is changing with time. In this context, one of the most used models is the Cox model (Cox, 1972) where the basic assumption for its use is that the failure rates are proportional. However…

Models based on hazard function have achieved great prominence in the survival analysis from the construction of the proportional hazards model of Cox (1972). One of the reasons this model has become so popular is its interpretative power and ease with which the technical difficulties arising from the censures were circumvented. Naturally, the construction of the model allows the covariat…
