What does fp_err_ctx do?

Post by aliakhavan89 »

When I estimate the parameters of a model using over-dispersed Poisson (attached), the optimizer generates 'fp_err_ctx' .cin files. But when I run the model with these inputs, I don't get any fp errors. I might be missing something, so could you please help me understand what's happening? Thank you!

These _should_ replicate an fp error. We'll take a look at the model. You might try turning on the payoff report, if it isn't already on, to reproduce.

Thank you very much, Tom! I didn't have the payoff report on, and I accidentally found out about the cin fp error files. But I didn't get any error when I used the .cin input to simply run the model, which was surprising. I can run the calibration with the payoff report on to see what else is being generated and will keep you posted. In the meantime, please let me know if I can provide any additional information.
Thanks again,
Ali
