从含加性噪声的数据中估计凹分布函数

Estimating a concave distribution function from data corrupted with additive noise

Geurt Jongbloed, Frank H. van der Meulen

摘要:

我们考虑两个非参数估计的凹分布函数的基础上损坏的数据与加性噪声产生的有界递减密度$(0,\infty)$的程序。对于最大似然(ML)估计和最小二乘(LS)估计,我们状态的定性性质,证明了一致性,并提出了一个计算算法。对于LS估计及其导数,我们也得到了点态渐近分布。此外,率$n^{-2/5}$实现的LS估计被证明是极小极大估计的分布函数在一个不动点。

英文摘要:

We consider two nonparametric procedures for estimating a concave distribution function based on data corrupted with additive noise generated by a bounded decreasing density on $(0,\infty)$. For the maximum likelihood (ML) estimator and least squares (LS) estimator, we state qualitative properties, prove consistency and propose a computational algorithm. For the LS estimator and its derivative, we also derive the pointwise asymptotic distribution. Moreover, the rate $n^{-2/5}$ achieved by the LS estimator is shown to be minimax for estimating the distribution function at a fixed point.
