***** To join INSNA, visit http://www.sfu.ca/~insna/ ***** Dear all, I have a question concerning the use of interaction terms in Multiple Regression among matrices (in particular using the UCINET QAP procedure). Is it correct to proceed as in normal statistics (i.e. standardizing the matrices and then multiplying the main effects)? Is there any empirical piece that adopted this procedure? What are the potential issues linked to the use of interaction terms? I thank in advance anyone who may have ideas or experience with that procedure. Alessandro Alessandro Usai Phd.
