Suppose Y=f(X,Z), where Z is a measurable vector, X is a latent random vector
which in turn is a function of other random vectors. Then what is the best
way to model the following relationship between X and Z, and their effects
on y:
It is assumed that X is compared against with Z, and (1) if the resulting
difference falls within a range, then the effect of the difference on Y is
weak or unimportant (2) if the difference is large, then it has strong or
