Semiparametric efficient estimation of genetic relatedness with machine learning methods
Xu Guo, Yiyuan Qian, Hongwei Shi +2
In this paper, we propose semiparametric efficient estimators of genetic relatedness between two traits in a model-free framework. Most existing methods require specifying certain…

Tests for ultrahigh-dimensional partially linear regression models
Hongwei Shi, Bowen Sun, Weichao Yang +1
In this paper, we consider tests for ultrahigh-dimensional partially linear regression models. The presence of ultrahigh-dimensional nuisance covariates and unknown nuisance functi…

Score function-based tests for ultrahigh-dimensional linear models
Weichao Yang, Xu Guo, Lixing Zhu
In this paper, we investigate score function-based tests to check the significance of an ultrahigh-dimensional sub-vector of the model coefficients when the nuisance parameter vect…
