Title: On bias prevention and incidental parameters.
Abstract: Firth (1993, Biometrika) introduced the bias prevention approach with the aim to reduce the bias of the maximum likelihood estimator. It is shown that the methodology is also effective in reducing the sensitivity of the derived inferential procedures in models involving incidental parameters.
