Hey, when running the hausman test, should I include all variables? So dependent, independent, moderator (how? with #?) and controll variables?
Do I need to define them somehow?
Because if I run the test like that I get the note: the rank of the differenced variance matrix (4) does not equal the number of coefficients being tested (5); be sure this is what you expect, or there may be problems computing the test. Examine the output of your estimators for anything unexpected and possibly consider scaling your variables so that the coefficients are on a similar scale.

Thank you!
