Summary of available dose response models

Basic characteristics of available dose response models are summarized here, sorted by pathogen. Each entry links to a page with more detailed information, including model fit, confidence intervals, and references.

The 'k or N50' column gives k if the model is exponential, or N50 if the model is beta-Poisson. Alpha is only applicable if the model is beta-Poisson. 'RD50' is the dose required for 50% of the hosts to suffer the response (like ID50 or LD50).
