I have a syntax with an interaction term over the attributes Distance and Price. It is known with certainty that these two attributes are inversely proportional to each other , it is not possible to increase them at the same time. How can we integrate this information to the given syntax to eliminate dominated alternatives from the output?
Design
;alts = alt1, alt2
;rows = 18
;eff = (mnl,d)
;block = 3
;model:
U(alt1) = b1[-0.5] * Price[5,10,20,30] + b2[-0.4] * Distance[0,50,100,200] + b3[0.1] * EmissionSaving[0,20, 40] + b4 * Price * Distance /
U(alt2) = b1 * Price + b2 * Distance + b3 * EmissionSaving + b4 * Price * Distance $
