Evaluating the model

Your previous model, poisson_glm_factor, suffered from overdispersion, with a calculated dispersion value of 86.79. Did adding an offset to your new model, poisson_glm_offset, account for unequal sampling effort solve this problem?

Note that the poisson_glm_offset model and custom function dispersion() have been preloaded.
