Is there any restriction for "proc mianalyze" such as
number of variables in input data? Because I ran
across such a problem in log file:
ERROR: The variable Col5 is not in the COVB= data set.
ERROR: The variable Col6 is not in the COVB= data set.
And I checked the data where there are only 4
explanatory variables. I can not get the results
from "proc mianalyze" due to the errors above.
The input data for "COVB" is got
from "proc mixed". What do
you think is wrong?
