This is a Lotka-Volterra model with an over-dispersed Poisson as payoff (I've shared a version of this model earlier). What does Vensim do when the event data is non-integer? I get these warnings at the very end of the estimation log: Thank you!

It still computes the payoff; fortunately that works because it uses the LogGamma function as a continuous generalization of factorial. Should be harmless, though perhaps we should suppress excessive warnings.

I understand it now. Thanks a lot for the clarification!
