Parameter estimation of Generalized Linear Model (Poisson distribution) for modeling the intensity of reproduction of wild-caught fruit-feeding butterflies held in captivity on sugar or banana diets, where E. medon fed sugar is treated as the baseline group. Overall, butterflies fed banana laid 1.269 times more eggs than those fed sugar on days that they laid any.
