Parameters estimation for modified weibull distribution based on singly type one censored samples


The three parameters distribution called modified Weibull distribution (MWD) introduced by sarhan and zaindin (2009). In this paper, we deal with point estimation to estimate the parameters of modified Weibull distribution based on complete data, using maximum likelihood method Ordinary least squares estimator method and rank set sampling estimator method to obtain the estimate parameters for modified Weibull distribution, then estimate the death function , survival function and hazard function obtained these estimate functions by applied on set of real data which taken for Leukemia disease in the Baghdad general hospital.
