In many data sets from clinical studies there are patients insusceptible to the occurrence of the event of interest. Survival models which ignore this fact are generally inadequate. The main goal of this paper is to describe an application of the generalized additive models for location, scale, and shape (GAMLSS) framework to the fitting of long-term(More)
In this paper, we propose a new cure rate survival model, which extends the model of Rodrigues et al. (2011) by incorporating a dependence structure between the initiated cells. To create the correlation structure between the initiated cells, we use an extension of the generalized power series distribution by including an additional parameter ρ(More)
The objective of this experiment was to test in vitro embryo production (IVP) as a tool to estimate fertility performance in zebu bulls using Bayesian inference statistics. Oocytes were matured and fertilized in vitro using sperm cells from three different Zebu bulls (V, T, and G). The three bulls presented similar results with regard to pronuclear(More)
For the first time, we formulate a flexible density function from the selection mechanism viewpoint (see, for example, Bayarri & DeGroot (1992) and Arellano-Valle et al. (2006)) which possesses nice biological and physical interpretations. The new density function contains as special cases many models that have been proposed recently in the literature. In(More)
