Trying to fit exponential decay growth model with estimator = bayes, can't get around this problem:
*** ERROR For analysis with ESTIMATOR=BAYES, NEW parameters must appear on the left-hand side in at least one MODEL CONSTRAINT equation. No equation found containing parameter on the left-hand side: ERATE
Is there a work-around?
MODEL: INIT BY ANX1@1; INIT BY ANX2-ANX5* (L12-L15);
Ah... that's a shame. I'll need to stick with ML then.
The issue that I'm getting with this approach (and hence the motivation for trying Bayesian estimation) is that I keep getting a negative variance estimate for RATE (and it's not very close to zero, so no quick 'fixing to close to 0' type solution seems correct!).
I've tried fixing it to be > 0 but then I get a correlation > 1 popping up...
