随机逼近方法定义的递归核密度估计的大偏差和中偏差原理

Large and moderate deviation principles for recursive kernel density estimators defined by stochastic approximation method

Yousri Slaoui

摘要:

在本文中,我们证明了由Mokkadem等人[2009]引入的随机逼近算法定义的概率密度函数的递归核估计的大偏差和中偏差原理。概率密度估计的随机逼近方法。J. Statistist.计划推论139,2459-2478]。我们证明了使用Mokkadem等人(2009)中定义的递归估计量类的方差最小化的步长构造的估计量给出了与Rosenblatt核估计量相同的逐点LDP和MDP。我们提供的点态和一致偏差的结果。

英文摘要:

In this paper we prove large and moderate deviations principles for the recursive kernel estimators of a probability density function defined by the stochastic approximation algorithm introduced by Mokkadem et al. [2009. The stochastic approximation method for the estimation of a probability density. J. Statist. Plann. Inference 139, 2459-2478]. We show that the estimator constructed using the stepsize which minimize the variance of the class of the recursive estimators defined in Mokkadem et al. (2009) gives the same pointwise LDP and MDP as the Rosenblatt kernel estimator. We provide results both for the pointwise and the uniform deviations.
