Robust Poisson Regression

Robust Poisson regression tilpasser en Poisson log-lineær model til et binært udfald, men erstatter den modelbaserede varians med den empiriske sandwich-estimator. Dette giver gyldige standardfejl og risikoforhold, selvom Poisson-variansantagelserne teknisk set er overtrådt for binære data. Tilgangen, populariseret af Zou (2004), bruges bredt i epidemiologi som et numerisk stabilt alternativ til log-binomial regression.
