摘要: Consider the two-sided truncation distribution families written in the form f(x,θ)=w(θ1, θ2h(x)I[θ1,θ2](x)dx, where θ=(θ1,θ2). T(X)=(t1(X), t2(X))=(min(X1, …, Xm), max(X1, …, Xm)) is a sufficient statistic and we denote its marginal density by f(t)dμT. The prior distribution of θ belong to the famlly J={G:∫∫Θ||θ||2dG(θ)<∞}. In this paper, we have constructed the empirical Bayes (EB) estimator of θ, φn(t), by using the kernel estimation of f(t) and established its convergence rates. Under suitable conditions it is shown that the rates of convergenc of EB estimator are O(N-((λk-1)(k+1))/(2(k+2)k)), where the neural number k > 1 and 1/2 < λ < 1-(1/2k). Finally an example about this result is given.

Abstract: Consider the two-sided truncation distribution families written in the form f(x,θ)=w(θ1, θ2h(x)I[θ1,θ2](x)dx, where θ=(θ1,θ2). T(X)=(t1(X), t2(X))=(min(X1, …, Xm), max(X1, …, Xm)) is a sufficient statistic and we denote its marginal density by f(t)dμT. The prior distribution of θ belong to the famlly J={G:∫∫Θ||θ||2dG(θ)<∞}. In this paper, we have constructed the empirical Bayes (EB) estimator of θ, φn(t), by using the kernel estimation of f(t) and established its convergence rates. Under suitable conditions it is shown that the rates of convergenc of EB estimator are O(N-((λk-1)(k+1))/(2(k+2)k)), where the neural number k > 1 and 1/2 < λ < 1-(1/2k). Finally an example about this result is given.
