WebJun 19, 2014 · The basic idea of the firth logistic regression is to introduce a more effective score function by adding an term that counteracts the first-order term from the asymptotic expansion of the bias of the maximum likelihood estimation—and the term will goes to zero as the sample size increases (Firth, 1993; Heinze and Schemper, 2002).
