Bayesian nonparametric inferential procedures based on Markov chain Monte Carlo marginal methods typically yield point estimates in the form of posterior expectations. Though very useful and easy to implement in a variety of statistical problems, these methods may suffer from some limitations if used to estimate non-linear functionals of the posterior distribution. The main goal is to develop a...

Graphical methods for model diagnostics are an essential part of the model fitting procedure. However, in survival analysis, the plotting is always hampered by the presence of censoring. Although model specific solutions do exist and are commonly used, we present a more general approach that covers all the models using the same framework. The pseudo-observations enable us to calculate residuals...

In this paper, a joint hazard-based model is proposed to analyze simultaneous (mutually interdependent) duration processes. The proposed model generalizes independent hazard based models by accounting for correlations between simultaneous duration processes. Further, the model also permits flexible and variable hazard function parameters to capture realistic features observed empirically in act...

Relative survival is the standard measure of excess mortality due to cancer in population-based cancer survival studies. In relative survival analysis, the observed hazard for cancer patients is the sum of the expected hazard for the general cancer-free population and the excess hazard associated with a cancer diagnosis. Previous models for relative survival analysis have assumed that the exces...

In epidemiologic studies, there is often more than one outcome measured on the same subject. Multiple failures from the same individual induce multivariate failure time data involving within-subject dependence. Furthermore, participants may not be independent within a cluster (e.g., as with members of the same family). Responses from subjects in the same cluster generate multivariate failure ti...

Flooding is one of the most occurring natural hazards every year risking the lives and properties of the affected communities, especially in Philippine context. To visualize the extent and mitigate the impacts of flood hazard in Malingon River in Valencia City, Bukidnon, this paper presents the combination of Geographic Information System, high-resolution Digital Elevation Model, land cover, so...
