We study the two-action problem in the exponential distribution via empirical Bayes (EB) approach. Based on typeⅡcensored samples, we construct an EB test rule and obtain an optimal rate of convergence which much improves the existing results in the literature.  相似文献

In this paper, the empirical Bayes (EB) two-sided test for parameter of Cox models is investigated under square loss functions. At first by using recursive kernel estimation of probability function the empirical Bayes two-sided test rule is constructed. It proves that the proposed empirical Bayes test rule is asymptotic optimal and convergence rates are obtained under suitable conditions. Finally an example of satisfying theorem conditions is given.  相似文献

In this paper, empirical Bayes test for a parameter θ of two-parameter exponential distribution is investigated with replicated past data. Under some conditions, the asymptotically optimal property is obtained. It is indicated that the rate of convergence can be very close to O(N-2^-1) in this case that a parameter μ is known.  相似文献

Empirical Bayes test for scale exponential family   总被引:1,自引:0,他引:1  
In this paper, we consider the empirical Bayes (EB) test problem for the scale parameters in the scale exponential family with a weighted linear loss function. The EB test rules are constructed by the kernel estimation method. The asymptotical optimality and convergence rates of the EB test rules are obtained. The main results are illustrated by applying the proposed test to type II censored data from the exponential distribution and to the test problem for the dispersion parameter in the linear regression model. __________ Translated from Journal of University of Science and Technology of China, 2004, 34(1): 1–10  相似文献

Consider k (k 2) populations whose mean i and variance i 2 are all unknown. For given control values 0 and 0 2 , we are interested in selecting some population whose mean is the largest in the qualified subset in which each mean is larger than or equal to 0 and whose variance is less than or equal to 0 2 . In this paper we focus on the normal populations in details. However, the analogous method can be applied for the cases other than normal in some situations. A Bayes approach is set up and an empirical Bayes procedure is proposed which has been shown to be asymptotically optimal with convergence rate of order O(ln2 n/n). A simulation study is carried out for the performance of the proposed procedure and it is found satisfactory.  相似文献
