Hello,
I'm new to longitudinal data and am trying to run a random coefficient
analysis via proc mixed in SAS. I get the "did not merge" error
message, which I realize (through reading google websites) can be for a
variety of reasons all involving modeling.
My question is what steps should be taken to overcome this
problem...i.e. if there isn't a simple command what secondary model
should be attempted?
Thanks
