Statistical Inference on High Dimensional Gaussian Graphical Regression Models
Xuran Meng, Jingfei Zhang, Yi Li
Gaussian graphical regressions have emerged as a powerful approach for regressing the precision matrix of a Gaussian graphical model on covariates, which, unlike traditional Gaussi…
An Eigengap Ratio Test for Determining the Number of Communities in Network Data
Yujia Wu, Jingfei Zhang, Wei Lan +1
To characterize the community structure in network data, researchers have introduced various block-type models, including the stochastic block model, degree-corrected stochastic bl…
A Preferential Latent Space Model for Text Networks
Maoyu Zhang, Biao Cai, Dong Li +2
Network data enriched with textual information, referred to as text networks, arise in a wide range of applications, including email communications, scientific collaborations, and…
High-dimensional covariance regression with application to co-expression QTL detection
Rakheon Kim, Jingfei Zhang
While covariance matrices have been widely studied in many scientific fields, relatively limited progress has been made on estimating conditional covariances that permits a large c…
