Hi all, I have logistically- regressed 3 different numerical variables ,v1,v2,v3 separately against the same variable w . All variables have the same type of S-curve (meaning, in this case, that probabilities increase as vi ; i=1,2,3 increases ). Is there a way of somehow joining the three variables v1,v2,v3 into a single variable V to be regressed against w? Specifically, w is a numerical measure of control methods in business , while v1 is theft, v2 is inefficiency, v3 is loss(money). Is there a meaningful way to get a new variable V to regress logistically against w? Thanks.
