WebJun 30, 2024 · We propose two simple modifications of Firth's logistic regression resulting in unbiased predicted probabilities. The first corrects the predicted probabilities by a post hoc adjustment of the intercept. The other is based on an alternative formulation of Firth's penalization as an iterative data augmentation procedure. WebSep 15, 2016 · Using Firths penalized likelihood instead of the ordinary likelihood is an option in the model statement in proc logistic. It is still binary logistic regression so it …
