diffR: Detect difference between two networks.

Description

Detecting significant different edges between two networks.

Usage

diffR(Data1,Data2,ALPHA1=0.05,ALPHA2=0.05)

Arguments

Data1

a \(n_1\)x\(p\) data matrix.

Data2

a \(n_2\)x\(p\) data matrix.

ALPHA1

The significance level of correlation screening for each dataset. In general, a high significance level of correlation screening will lead to a slightly large separator set \(S_{ij}\), which reduces the risk of missing some important variables in the conditioning set. Including a few false variables in the conditioning set will not hurt much the accuracy of the \(\psi\)-partial correlation coefficient.

ALPHA2

The significance level of \(\psi\) screening for integrative estimation of \(\psi\) scores.

Value

A

\(p\)x\(p\) adjacency matrix of the combined graph.
