Abstract: | In this paper, the definition of E-Bayesian estimation of the parameter is provided; moreover, for Pareto distribution, under the condition of the scale parameter is known, based on the square error loss function, formulas of E-Bayesian estimation and hierarchical Bayesian estimation for the shape parameter are also pro-vided, and using the Monte Carlo method simulation example is given. Finally, combined with the golfer income data practical problem are calculated, the results show that the proposed method is feasible and convenient for application. |
