Hi, Luke.

You did not give us the -xtprobit- command that you used.  If the
regression involves other predictors besides that dummy variable, it
may not be surprising that the coefficient of the dummy variable does
not have the sign that you expect.  That coefficient should be
interpreted as the effect of the dummy variable after adjusting for
simultaneous linear change in the other predictors in your model.
