A search of available programs -search Gregory Hansen- suggests that -ghansen- (SSC, as you are asked to describe) is the only package available for this test. Not being familiar with it, you must either make do with 4 variables or go to the literature to see if it is possible/sensible to extend the test. Someone else on the forum may be able to offer a solution.
