Abstract: This study proposes integer-valued transfer function models with zero-inflated generalized Poisson and negative binomial distributions to help describe overdispersion, a large proportion of zeros, and the influence of exogenous variables. We provide effective Bayesian estimation and model selection for weekly dengue cases with two meteorological covariates.
