Improved Horvitz-Thompson Estimator in Survey Sampling
Xianpeng Zong, Rong Zhu, Guohua Zou
The Horvitz-Thompson (HT) estimator is widely used in survey sampling. However, the variance of the HT estimator becomes large when the inclusion probabilities are highly heterogen…
Optimal Subsampling for Large Sample Logistic Regression
HaiYing Wang, Rong Zhu, Ping Ma
For massive data, the family of subsampling algorithms is popular to downsize the data volume and reduce computational burden. Existing studies focus on approximating the ordinary…
Optimal Subsampling Approaches for Large Sample Linear Regression
Rong Zhu, Ping Ma, Michael W. Mahoney +1
A significant hurdle for analyzing large sample data is the lack of effective statistical computing and inference methods. An emerging powerful approach for analyzing large sample…
Semiparametric Small Area Estimation of Crop Acreage under Partially Linear Model
Rong Zhu, Guohua Zou, Chun Wang +1
Small area estimation under linear mixed models often assumes that the small area effect is random effect in almost all previous studies. However, in this paper a new approach is p…
