Overdispersed Poisson modelIn the Poisson model for loss reserving it is assumed that the incremental claims are independent and Poisson distributed with expectations being the product of two factors, depending
Model:I would like to fit the modely ~ x1 + I(x1^2) + x2in order to test the associations of the two predictor variables withy. Approach:Initially I fitted a poisson-family GLM. A residual qq plot indicated non-normal residuals and suggested right-skew. I therefore tested for overdisp...
we utilize a covariate-augmented overdispersed Poisson factor model. We distinguish between high-dimensional covariates sharing similar attributes and those serving as control variables to enrich the representation learning process. To capture the spatial dependency of each variable across different locations...
Generalized Poisson modelNegative binomial modelOverdispersionPoisson modelScore testZero-inflationThe negative binomial (NB) model and the generalized Poisson (GP) model are common alternatives to Poisson models when overdispersion is present in the data. Having accounted for initial overdispersion, we may...
Count data is often considered to have a Poisson distribution and Poisson regression is commonly used to model count data, but such data often exhibits more variability than expected under that distribution. This is known as overdispersion. Underdispersion can also occur when there is less ...

model. To this end, we performed AIC model selection using the glm() and stepAIC() (from the MASS package) functions in R. The identified best model was subsequently fitted within a Bayesian framework. We compare the results from this best model to that of a Poisson model without any ...
