局部双线性多输出分位数/深度回归

Local bilinear multiple-output quantile/depth regression

Marc Hallin, Zudi Lu, Davy Paindaveine, Miroslav Šiman

摘要:

一个新的分位数回归的概念,基于定向版本的Koenker和巴塞特的传统的单输出之一,已被引入[安。(2010)38 635-669],用于多输出位置/线性回归问题。然而,由该概念的经验对应物提供的多面体轮廓不能适应未知的非线性和/或异方差依赖性。因此,本文介绍了当地常数和当地的线性(实际上,双线性)版本的轮廓,这两个允许渐近恢复的条件半空间深度轮廓,完全表征响应的条件分布。建立了Bahadur表示和渐近正态性结果。在模拟和真实数据上都提供了插图。

英文摘要:

A new quantile regression concept, based on a directional version of Koenker and Bassett's traditional single-output one, has been introduced in [Ann. Statist. (2010) 38 635-669] for multiple-output location/linear regression problems. The polyhedral contours provided by the empirical counterpart of that concept, however, cannot adapt to unknown nonlinear and/or heteroskedastic dependencies. This paper therefore introduces local constant and local linear (actually, bilinear) versions of those contours, which both allow to asymptotically recover the conditional halfspace depth contours that completely characterize the response's conditional distributions. Bahadur representation and asymptotic normality results are established. Illustrations are provided both on simulated and real data.
