The shape parameter estimation using the minimum-variance linear estimator with hyperparameter (MVLE-H) method is believed to be effective for a wear-out failure period in small sample. In process of estimation, our uses and estimate parameters MVLE-H method. To obtain optimal c, it takes long time, even case main purpose this paper remove restriction samples. We observed that if we set paramet...

A measure of the predictive capability of a proportional hazards regression is derived. The measure is based on the residuals appropriate to proportional hazards regression. A population version is presented and can be seen not to depend on the censoring mechanism under the provision that any such censoring be independent or conditionally independent of the failure mechanism given the covariate...
