WinBUGS Programs

This page contains WinBUGS code for running various zero-inflated and hurdle models.

Zero-Inflated Count Models
  1. Zero-inflated Poisson model.zip presented in Neelon, O'Malley, and Normand (2010), Statistical Modelling.
    • Note 1: This file contains both ODC and data files.
    • Note 2: Initial values are at bottom of ODC file.
    • Note 3: You'll have to run the MCMC chain for at least 4000 iterations to get past the "adapting" phase.

  2. Poisson Hurdle and Zero-altered Poisson (ZAP) Models.zip: Fits hurdle and ZAP models as described in Neelon et al. (2010) Statistical Modelling.

  3. Spatial Poisson Hurdle.zip: Winbugs and R2WinBUGS code and data for fitting the spatial Poisson hurdle model as described in Neelon et al. (2012) A Spatial Poisson Hurdle Model for Exploring Geographic Variaton in Emergency Department Visits.

  4. Spatial NB Hurdle.zip: Fits NB Hurdle Model with CAR Random Effects via R2WinBUGS. See ReadMe.txt for details.

  5. ST_Hurdle.zip: Winbugs and R2WinBUGS code and data for fitting the spatiotemporal hurdle models described in Neelon et al. (2012) A Spatiotemporal hurdle models for zero-inflated count data: exploring trends in emergency department visits.
