Integer-valued transfer function models for counts that show zero inflation

This study proposes integer-valued transfer function models with zero-inflated gen-eralized 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. (c) 2022 Elsevier B.V. All rights reserved.
