考虑了一类特殊的反褶积模型--指数反褶积模型中分布函数的保序估计。第一个估计量是分布函数的朴素估计量在分布函数集合上的最小二乘投影。第二个估计量是众所周知的最大似然估计量。证明了这两个估计量在固定点处是一阶渐近等价的。
Two isotonic estimators for the distribution function in a specific deconvolution model, the exponential deconvolution model, are considered. The first estimator is a least squares projection of a naive estimator for the distribution function on the set of distribution functions. The second estimator is the well known maximum likelihood estimator. The two estimators are shown to be first order asymptotically equivalent at a fixed point.
