Modelo de regressao Weibull discreto com fracao de cura em dados de sobrevivencia

This paper presents a regression model for discrete time data with cure fraction. For this purpose, we considered a mixture model, in which times are modeled through the discrete Weibull distribution and the cure probability modeled with covariates by using the logit link function. Considering that...
