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.
