Using Different Methods to Estimate the Parameters of Probability Death Density Function with Application

Abstract

Abstract In this paper, we derive a formula for estimating the two parameters (λ,γ) for two parameter's Weibull, where (λ) is scale parameter and (γ) is shape parameter using the method of maximum likelihood and White estimators and Bayesian estimator, where (λ) is considered as random variable having prior distribution [g(λ)], the Bayes estimator of (λ) is derived according to squared error function, and then the estimators are applied to the set of data represent relief time (in hours) for (20) patient suffering from headache pain, we found that White method is simplest method.
