摘要
本文考虑了在一类加权损失函数下,某些离散分布族(包括Poisson分布、负二项分布,多元负二项分布等)均值参数的同时估计问题,并给出了关于损失函数和样本分布族稳健的优于通常估计量的改进估计量。
The present paper focuses on the simbltaneous estimation of mean parameters of some discrete distribution (includs Poisson distribution, multivariate negative binomial distribution) under a class of weighted loss functions. We give some robust improved estimators with respect to the sample distribution and the loss function.
