Specification testing for regression models with dependent data
收藏 引用
JOURNAL OF ECONOMETRICS 2008年 第1期143卷 143-165页
作者: Hidalgo, J. London Sch Econ Dept Econ London WC2A 2AE England
We examine a consistent test for the correct specification of a regression function with dependent data. The test is based on the supremum of the difference between the parametric and nonparametric estimates of the re... 详细信息

Semiparametric Double Balancing Score Estimation for Incomplete Data With Ignorable Missingness
收藏 引用
JOURNAL OF THE AMERICAN STATISTICAL ASSOCIATION 2012年 第497期107卷 247-257页
作者: Hu, Zonghui Follmann, Dean A. Qin, Jing NIAID Biostat Res Branch NIH Bethesda MD 20892 USA
When estimating the marginal mean response with missing observations, a critical issue is robustness to model misspecification. In this article, we propose a semiparametric estimation method with extended double robus... 详细信息

Sequential design for local bandwidth response curve estimator
收藏 引用
JOURNAL OF nonparametric STATISTICS 2000年 第4期12卷 539-548页
作者: Park, DR Hanshin Univ Dept Stat Osan 447791 Kyunggi Do South Korea
Suppose we want to estimate the response curve using a kernel estimator. When we perform an experiment to estimate the response curve, we usually decide on the location of all the design points in advance of the exper... 详细信息

JOURNAL OF FORECASTING 2012年 第2期31卷 172-188页
作者: Matias, Jose M. Reboredo, Juan C. Univ Santiago de Compostela Dept Econ Santiago De Compostela 15782 Spain Univ Vigo Dept Stat ETSEM Vigo 36310 Spain
We studied the predictability of intraday stock market returns using both linear and nonlinear time series models. For the S&P 500 index we compared simple autoregressive and random walk linear models with a range... 详细信息

TEST 2001年 第1期10卷 161-182页
作者: Rodríguez-Poo, JM Linton, O Univ Cantabria Dept Econ E-39005 Santander Spain Univ London London Sch Econ & Polit Sci Dept Econ London WC2A 2AE England
We introduce a nonparametric smoothing procedure for nonparametric factor analysis of multivariate time series. Our main objective is to develop an adaptive method for estimating a time-varying covariance matrix. The ... 详细信息

Estimation of mean response via the effective balancing score
收藏 引用
BIOMETRIKA 2014年 第3期101卷 613-624页
作者: Hu, Zonghui Follmann, Dean A. Wang, Naisyin NIAID Biostat Res Branch NIH Bethesda MD 20892 USA Univ Michigan Dept Stat Ann Arbor MI 48109 USA
We introduce the effective balancing score for estimation of the mean response under a missing-at-random mechanism. Unlike conventional balancing scores, the proposed score is constructed via dimension reduction free.... 详细信息

Sufficient dimension reduction and instrument search for data with nonignorable nonresponse
收藏 引用
BERNOULLI 2021年 第2期27卷 930-945页
作者: Zhao, Puying Wang, Lei Shaw, Jun Yunnan Univ Dept Stat Kunming Yunnan Peoples R China Nankai Univ Sch Stat & Data Sci Tianjin Peoples R China Univ Wisconsin Dept Stat Madison WI 53706 USA
Consider a response variable subject to nonignorable nonresponse and a fully observed covariate vector. The purpose of our study is threefold. First, we study how to extend nonparametric sufficient dimension reduction... 详细信息

nonparametric causal inference from observational time series through marginal integration
收藏 引用
ECONOMETRICS AND STATISTICS 2017年 2卷 81-105页
作者: Li, Shu Ernest, Jan Buehlmann, Peter Swiss Fed Inst Technol Seminar Stat Ramistr 101 CH-8092 Zurich Switzerland
Causal inference from observational data is an ambitious but highly relevant task, with diverse applications ranging from natural to social sciences. Within the scope of non-parametric time series, causal inference de... 详细信息
