ZIHINAR1: Zero-Inflated and Hurdle INAR(1) Models

Provides tools for estimating Zero-Inflated INAR(1) (ZI-INAR(1)) and Hurdle INAR(1) (H-INAR(1)) models using 'Stan'. It allows users to simulate time series data for these models, estimate parameters, and evaluate model fit using various criteria. Functions include model estimation, simulation, and likelihood-based metrics. The zero-inflated and hurdle INAR(1) methods are described by Yang et al. (2025) <doi:10.1214/25-BJPS646>. Zero-inflated models also support Conway-Maxwell-Poisson innovations.
