ERROR -- Multiple strata within one primary session
Posted: Wed Oct 09, 2019 12:21 pm
Hi, I'm running an MSORD, with weekly sampling intervals as secondary sessions, and years as primary sessions. My states are 1 (encountered) and U (unobserved).
When I try to run the models I get the following error;
ERROR -- Multiple strata within one primary session.
STOP ERROR
I haven't had this before (when I have run similar models which an individual has been U in one secondary and then 1 in another secondary within the same primary sessions it's been fine.I don't understand the error and can't seem to work out how to fix this. I'm incredibly stuck!
Any advice would be really appreciated.
Thanks so much,
Jess
