interpreting GC path coefficients

Submitted by ma.shalchy on Thu, 01/01/2015 - 10:50

Dear experts
Since I do not see a negative path coefficient in any related paper, I have difficulty interpreting the results. i.e if tvalue of ROI1 vs ROI2  path coefficient  is -0.8 and ROI2 vs ROI1 coefficient is +0.003 how should I assess the overall effective connectivity (direction and srength)?
 
Many thanks in advance,
mahsa
