چکیده
The maximum likelihood estimator MLE for the survival function ST under the proportional hazards model of censorship is derived and shown to di er from the Abdushukurov Cheng Lin estimator when the class of allowable distributions includes all continuous and discrete distributions The estimators are compared via an example The MLE is calculated using a Newton Raphson iterative procedure and implemented via a FORTRAN algorithm

Estimation in the Koziol-Green model using a gamma process prior
The paper deals with nonparametric Bayes estimators in the KoziolGreen model of random censorship. A gamma process is assumed as a prior distribution for cumulative hazard rate and the Bayes estimator incorporating the proportional hazards censorship property of the model is presented. The estimator is also applied to two data sets from literature.
متن کاملLinear Wavelet-Based Estimation for Derivative of a Density under Random Censorship
In this paper we consider estimation of the derivative of a density based on wavelets methods using randomly right censored data. We extend the results regarding the asymptotic convergence rates due to Prakasa Rao (1996) and Chaubey et al. (2008) under random censorship model. Our treatment is facilitated by results of Stute (1995) and Li (2003) that enable us in demonstrating that the same con...

متن کاملExponential semiparametric regression models under random censorship∗
Using the weighted maximum likelihood method, we propose a consistent estimation of parametric portion and nonparametric portion in exponential semiparametric regression models under random censorship. A small Monte Carlo study is carried out to examine the proposed estimation method.
متن کاملBayesian Estimation in the Proportional Hazards Model of Random Censorship under Asymmetric Loss Functions
In this paper, we consider the Bayesian estimation of parameters in the proportional hazards model of random censorship for the Weibull distribution under different asymmetric loss functions. It is well-known for the Weibull distribution that a joint conjugate prior on the parameters does not exist; we use both the informative and noninformative priors on the model parameters. Bayes estimates u...
