Hi,
I would like to know whether the Degree Centrality calculation is based on positive correlations only, or also on negative correlations? If I set a correlation threshold of r=0.2 will it take the absolute values of correlation and include negative correlations as well? If no, is there a way to calculate DC taking into account both positive and negative correlations at the same time?
Kind regards,
Anja Ries

Re: Degree Centrality and negative correlations
Yes, it only computes positive correlations (both positive weighted and binary) by default. If you consider both positive and negative correlations, you can use the gretna toolbox.
