Model selection metrics for hurdle count regression models fit to occurrence and abundance data for steelhead redds at 209 sites in the John Day River basin, Oregon.

1Model results are ranked by AICc from best to worst, and Akaike weights (wi,)>0.05 are also shown.2K is the number of estimated parameters, L-L is the log-likelihood, and ΔAICc is the difference in AICc relative to the best model (see [41] for details).
