WebA procedure by Firth (1993) originally developed to reduce the bias of maximum likelihood estimates is shown to provide an ideal solution to monotone likelihood (cf. Heinze & Schemper, 2001, 2000). It produces finite parameter estimates by means of penalized maximum likelihood estimation. WebThis procedure calculates the Firth logistic regression model, which can address the separation issues that can arise in standard logistic regression.
