Solution 2: Try suest. n, cl(idcode) Suest test Same as Hausman but comparing coefficient in common coefficients; can compare model with and without one variable or have a test that only looks at one coefficient; instead of comparing all, looking at coefficients for one variable which you cannot do with Suest.
