Testing for equal correlation matrices with application to paired gene expression data
Adria Caballe, Natalia Bochkina, Claus Mayer +1
We present a novel method for testing the hypothesis of equality of two correlation matrices using paired high-dimensional datasets. We consider test statistics based on the averag…

Joint Estimation of Sparse Networks with application to Paired Gene Expression data
Adria Caballe, Natalia Bochkina, Claus Mayer
We consider a method to jointly estimate sparse precision matrices and their underlying graph structures using dependent high-dimensional datasets. We present a penalized maximum l…

Selection of the Regularization Parameter in Graphical Models using Network Characteristics
Adria Caballe, Natalia Bochkina, Claus Mayer
Gaussian graphical models represent the underlying graph structure of conditional dependence between random variables which can be determined using their partial correlation or pre…
