Converts precision matrix to partial correlation matrix
Description
A small function that converts a precision matrix (inverse of covariance matrix) to a partial correlatin matrix. This can be done by standardizing the precision matrix and changing the sign of the offdiagonal entries. Many methods exist for obtaining a precision matrix (Such as the glasso package; Friedman, Hastie and Tibshirani, 2011) but the partial correlation matrix is easier interpretable and better usuable in qgraph.
Usage
wi2net(x)
Arguments
x
A precision matrix
Value
A partial correlation matrix
