I am not sure it is a good idea to send a new topic before getting an answer to the first one. I apologize for that and hope these issues may be of some general interest.
This is my data specifications:
1 group,
0 individual covariates,
3 states,
4 events (not seen, no antibodies, antibodies, unknown)
1 age class
9 occasions
I am running an analysis in E-Surge whose pattern matrices are defined in GEPAT just like this (copied and pasted from another thread):
I have defined in GEMACO these sentences (in capital letters the pattern matrices):
INITIAL t
SURVIVAL f.t
TRANSITION f.t
CAPTURE f.t
STATE ASSIGNMENT f.t
the problem arises from the results I get with state assignment (event, step 2), that are these:
I can't understand why there is an age effect that (i) I have no specified and (ii) I have set just one age class in the data.
Anyway, in order to remove the age effect, I have tried to set:
STATE ASSIGNMENT [a(1:2)].f.t
but the result is just the same, why?
Thanks for any help,
Simone
