Solis-Trapala, Ivonne L. and Farewell, Vernon T. (2006) A note on Robust Inference from a conditional Poisson Model. Biometrical Journal, 48 (1). pp. 117-130. ISSN 1521-4036

Abstract

A randomised controlled trial to evaluate a training programme for physician-patient communication required the analysis of paired count data. The impact of departures from the Poisson assumption when paired count data are analysed through use of a conditional likelihood is illustrated. A simple approach to providing robust inference is outlined and illustrated.
