Estimate survival function for censored sample type two Bladder cancer

Abstract

                This research cares to estimate the unlabeled parameters for generalized Rayleigh distribution model depend on censored samples type two ; Utilizing the maximum likelihood estimator method  to get the derivation of the point estimation for all unlabeled parameters depend on iterative technique , as Newton – Raphson method , then to derive Lindley approximation estimator method  . At last , checking whether this model ( GRD ) suits to a set of real data .
