st: testing for presence AND degree of endogeneity

I am estimating a model of choice 1 (j alternatives) and choice 2 (k
alternatives) for i individuals, as follows.

(1) choice 1_i = f(X_i, Z_i, attributes of choice 1_j)

(2) choice 2_i= f(X_i, W_i, attributes of choice 2_k, choice 1_i)

The dependent vars in (1) and (2) are categorical. I have a strong
indication that choice 1 is endogenous. Of course, I would like to
test for endogeneity, but more importantly, I want to determine the
DEGREE of endogeneity. Is there a way to determine the presence and
degree of endogeneity?

Thanks in anticipation,
