Is offset available for NB? She has tried to model it by constraining the regression coefficient of the log(exposure) to 1 but the model did not converge. Thank you, Margarita & Alex Bengt O. Muthen posted on Wednesday, December 19, 2018 - 3:39 pm Yes, fixing the log(exposure) ...

Poisson regression programs allow for this through something called an offset. An offset is variable that is forced to have a regression coefficient of 1. Here, it contains the (natural) logarithm of the time on study. Then, the fitted equation will be ...
