Mathematically, you can transform any effect you want. However,&nbsp;the resulting effect might be difficult to interpret.</P> <P>&nbsp;</P> <P>A log transformation of an interaction might be reasonable because log(X*Y) = log(X) + log(Y).&nbsp;</P> Fri, 07 Jul 2017 18:34:37 GMT https://communities.sas.com/t5/SAS-Data-Science/Transformations-of-two-way-interractions/m-p/374065#M5563 Rick_SAS 2017-07-07T18:34:37Z
