Abstract: The point estimation of the parameter θ of the uniform distribution U(0, θ) is discussed. The general form of the Bayesian estimation of θ is investigated under the weighted square loss function in the framework of Bayesian statistics, and the precise form of the Bayesian estimation of θ is obtained based on the given Pareto conjugate prior distribution. The comparisons between the Bayesian estimation that obtained in the framework of Bayesian statistics and the maximum likelihood estimation that obtained in the framework of classical statistics are studied from theory and simulation respectively. Results show that the Bayesian estimation of θ under the weighted square loss function is smaller than the maximum likelihood estimation of θ in the framework of classical statistic in numerical value, and the Bayesian estimation that obtained is the maximum likelihood estimations of the corresponding functions of θ, respectively.
