Interaction Pursuit Biconvex Optimization
Yuehan Yang, Siwei Xia, Hu Yang
Multivariate regression models are widely used in various fields such as biology and finance. In this paper, we focus on two key challenges: (a) When should we favor a multivariate…
Sparse Laplacian Shrinkage with the Graphical Lasso Estimator for Regression Problems
Yuehan Yang, Siwei Xia, Hu Yang
This paper considers a high-dimensional linear regression problem where there are complex correlation structures among predictors. We propose a graph-constrained regularization pro…
Smooth Adjustment for Correlated Effects
Yuehan Yang, Hu Yang
This paper considers a high dimensional linear regression model with corrected variables. A variety of methods have been developed in recent years, yet it is still challenging to k…
Semiparametric model averaging for high dimensional conditional quantile prediction
Jingwen Tu, Hu Yang, Chaohui Guo
In this article, we propose a penalized high dimensional semiparametric model average quantile prediction approach that is robust for forecasting the conditional quantile of the re…
A note on the condition number of the scaled total least squares problem
Shaoxin Wang, Hanyu Li, Hu Yang
In this paper, we consider the explicit expressions of the normwise condition number for the scaled total least squares problem. Some techniques are introduced to simplify the expr…
On the condition number theory of the equality constrained indefinite least squares problem
Shaoxin Wang, Hanyu Li, Hu Yang
In this paper, within a unified framework of the condition number theory we present the explicit expression of the projected condition number of the equality constrained indefinite…
