“…The approach in many fields of study is to use a count regression model instead of a linear regression model. For example, in health-related studies, count regression models have been used to model the number of incidents of physical aggression or substance abuse (Gagnon, Doron-LaMarca, Bell, O'Farrell, & Taft, 2008), the number of malaria cases (Achcar, Martinez, Pires de Souza, Tachibana, & Flores, 2011), the number of medically attended childhood injuries (Karazsia & van Dulmen, 2008), number of health benefits received per patient (Czado, Schabenberger, & Erhardt, 2014), and number of sub-health symptoms (Xu, Li, & Chen, 2011). In other fields of study, they have also been used to estimate recreational trip demands (Wang, Li, Little, & Yang, 2009), number of auto insurance claims (Meng, 2009), number of roadway accidents (Nassiri, Najaf, & Amiri, 2014), and number of hardware failures or occurrences of disease or death (Gulkema & Goffelt, 2008).…”
