WebAug 17, 2024 · Logistic regression is a standard method for estimating adjusted odds ratios. Logistic models are almost always fitted with maximum likelihood (ML) software, which provides valid statistical inferences if the model is approximately correct and the sample is large enough (e.g., at least 4–5 subjects per parameter at each level of the … WebApr 5, 2024 · Firth (1993) suggested a modification of the score equations in order to reduce bias seen in generalized linear models. Heinze and Schemper (2002) suggested using Firth's method to overcome the problem of "separation" in logistic regression, a condition in the data in which maximum likelihood estimates tend to infinity (become …
