Note: the rank of the differenced variance matrix (11) does not equal the number of coefficients being tested (12); 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.
