Abstract:
|
Inflated count distributions are used in situations where counts of an underlying distribution of a population are larger than expected by traditional count distributions, a situation often observed for high risk health behaviors. One of the most commonly used inflated count distributions is the zero-inflated Poisson distribution. This work demonstrates the construction of a small count inflated Poisson distribution, of which the zero-inflated Poisson distribution is a special case. Model construction and parameter estimation are shown. Simulations analyzing asymptotic properties, group prediction, and count prediction are presented. Conclusions and recommendations for future research are discussed.
