This paper proposes a new procedure for computing the Cox statistic fo
r tests of nonnested hypotheses using the method of stochastic simulat
ion. The procedure is applicable to a wide class of probability distri
butions, is relatively simple to implement, and does not require an an
alytic derivation of the pseudo-true estimators that enter the Cox tes
t statistic. The paper also contains an application of the proposed me
thod to the test of probit versus logistic formulations of the univari
ate binary choice models. The empirical results show that the simulati
on method works reasonably well even for a moderate number of replicat
ions.
