provide the following information in full detail:

1. A full description of why the Poisson form of analysis (type of GLM or GLMM) was used. This should address the characteristics of the response and/or explanatory variables that suggested this form of analysis.
2. A listing or sample of the models that were compared with the regression analysisthe Poisson form of analysis (type of GLM)
