An Empirical Likelihood Approach to Nonparametric Covariate Adjustment in Randomized Clinical Trials
Xiaoru Wu, Zhiliang Ying
Covariate adjustment is an important tool in the analysis of randomized clinical trials and observational studies. It can be used to increase efficiency and thus power, and to redu…
Learning Item-Attribute Relationship in Q-Matrix Based Diagnostic Classification Models
Jingchen Liu, Gongjun Xu, Zhiliang Ying
Recent surge of interests in cognitive assessment has led to the developments of novel statistical models for diagnostic classification. Central to many such models is the well-kno…
Sequential Analysis of Cox Model under Response Dependent Allocation
Xiaolong Luo, Gongjun Xu, Zhiliang Ying
Sellke and Siegmund (1983) developed the Brownian approximation to the Cox partial likelihood score as a process of calendar time, laying the foundation for group sequential analys…
Rapid Learning with Stochastic Focus of Attention
Raphael Pelossof, Zhiliang Ying
We present a method to stop the evaluation of a decision making process when the result of the full evaluation is obvious. This trait is highly desirable for online margin-based ma…
