Optimal Network Pairwise Comparison
Jiashun Jin, Zheng Tracy Ke, Shengming Luo +1
We are interested in the problem of two-sample network hypothesis testing: given two networks with the same set of nodes, we wish to test whether the underlying Bernoulli probabili…
Power of Knockoff: The Impact of Ranking Algorithm, Augmented Design, and Symmetric Statistic
Zheng Tracy Ke, Jun S. Liu, Yucong Ma
The knockoff filter is a recent false discovery rate (FDR) control method for high-dimensional linear models. We point out that knockoff has three key components: ranking algorithm…
On Posterior Consistency of Bayesian Factor Models in High Dimensions
Yucong Ma, Jun S. Liu
As a principled dimension reduction technique, factor models have been widely adopted in social science, economics, bioinformatics, and many other fields. However, in high-dimensio…
Estimation of the number of spiked eigenvalues in a covariance matrix by bulk eigenvalue matching analysis
Zheng Tracy Ke, Yucong Ma, Xihong Lin
The spiked covariance model has gained increasing popularity in high-dimensional data analysis. A fundamental problem is determination of the number of spiked eigenvalues, . For…
