Cure Fraction Models Using Mixture and Non-mixture Models
We introduce the Weibull distributions in presence of cure fraction, censored data and covariates. Twomodels are explored in this paper: mixture and non-mixture models. Inferences for the proposed models are obtained under the Bayesian approach, using standard MCMC (Markov Chain Monte Carlo) methods. An illustration of the proposed methodology is given considering a lifetime data set.
متن کاملDeterminant of flexible Parametric Estimation of Mixture Cure Fraction Model: An Application of Gastric cancer Data
Cure models are survival models basically developed to estimate the proportion of patients cured in a clinical trial. These models estimate the cured proportion and also the probability of survival. Cure models are a special type of survival analysis model where it is assumed that there are a proportion of subjects who will never experience the event and thus the survival curve will eventually ...
متن کاملDetermining the correlated factors of breast cancer recurrence by Poisson Beta-Weibull non- mixture cure model
Introduction: Therapies for many of diseases, especially cancer, have been improved significantly in the recent years, resulting in an increase in the number of patients who do not experience mortality. Therefore, the application of cure models is more suitable for survival analysis in this population than the usual survival models are. The aim of this study was to estimate the recurrence-free ...

background & aim: esophageal cancer is one of the main common causes of death. the high prevalence of esophageal cancer in northern iran is an important public health problem. the main aim of this paper was to assess the factors affecting survival of atients with esophageal cancer in neighbor provinces around the caspian sea using weibull mixture cure model and mixture cure model based on a no...
متن کاملTransmuted exponentiated modified Weibull distribution with an application to bladder cancer data
This research investigates the potential usefulness of the transmuted exponentiated modified Weibull (TEMW) distribution for modelling bladder cancer data. This distribution, formed using the quadratic rank transmutation map technique, contains twenty three lifetime distributions as special cases. We obtain the analytic shapes of the density and hazard functions. Some structural properties of t...
