I am assuming that I an expected utility form between probabilities and payoff.
My attributes here are the probability (p) of an outcome and the outcome itself (X) plus an alternative outcome (Y).
Further, utility here can be for example u(x)=x^a and further probability p can be distorted in a non-linear function w(p)=p^b.
Hence, I have EU=p^b*(x^a-y^a)+y^a
Is there a way to specify a design in sawtooth for this type of models?
