Dear Andrew:

     Is the correlation calculated by NBS based on the Pearson correlation or Spearman rank-order correlation ? Thanks for help.

Hi Jay,

Pearson. Correlation is computed using the GLM, which is effectively Pearson.

      Thank you for your reply. The reason I asked this question is that my advisor thinks the behavior scores are discrete and the Spearman rank-order correlation should be used to perform the correlation analysis between the network strength and the behavior scores. I have read all the related threads in this archive. I believe my advisor is wrong but I don't know how to explain to her. Could you give me some hints? Thanks for help.

Hi Jay, this seems to be a question that might be more appropriate for a forum on statistics.

You could simply populate your design matrix with the rank of the behaviour scores (rather than the actual scores). This won't be exactly Spearman, but might alleviate some of the concerns.
