Estimation, Confidence Intervals, and Large-Scale Hypotheses Testing for High-Dimensional Mixed Linear Regression
Linjun Zhang, Rong Ma, T. Tony Cai +1
This paper studies the high-dimensional mixed linear regression (MLR) where the output variable comes from one of the two linear regression models with an unknown mixing proportion…
A Convex Optimization Approach to High-Dimensional Sparse Quadratic Discriminant Analysis
T. Tony Cai, Linjun Zhang
In this paper, we study high-dimensional sparse Quadratic Discriminant Analysis (QDA) and aim to establish the optimal convergence rates for the classification error. Minimax lower…
High-dimensional Linear Discriminant Analysis: Optimality, Adaptive Algorithm, and Missing Data
T. Tony Cai, Linjun Zhang
This paper aims to develop an optimality theory for linear discriminant analysis in the high-dimensional setting. A data-driven and tuning free classification rule, which is based…
A Sparse PCA Approach to Clustering
T. Tony Cai, Linjun Zhang
We discuss a clustering method for Gaussian mixture model based on the sparse principal component analysis (SPCA) method and compare it with the IF-PCA method. We also discuss the…
