"Not enough group counts..."

Postby not_present » Wed Feb 08, 2017 11:55 pm

Hi-

I am trying to run a multi-state model. I only have one group. However, whenever I try to run a model, I receive the following error:"Not enough group counts specified on the encounter history." I cannot find an explanation for this.
I have 96 occasions and 8 states. The .inp is formatted correctly, I think. My encounter history is a string containing: 0,A,B,C,D,E,F,G
Can anyone offer any insight? Thanks.

Sure -- because you don't actually have 8 states: A, B, C, D, E, F, G are your states (7 in total) -- the 0 is not a state.

Try again, this time specifiying 7 states, not 8.

Well, hopefully is does -- '0' is never a 'state', since it always denotes non-detection. You can have states that are unobservable, for where the detection probability is logically 0, but again, these would not be given a state of '0'.
