An investigation of penalization and data augmentation to improve convergence of generalized estimating equations for clustered binary outcomes
Abstract Background In binary logistic regression data are ‘separable’ if there exists a linear combination of explanatory variables which perfectly predicts the observed outcome, leading to non-existence of some of the maximum likelihood coefficient estimates. A popular solution to obtain finite es...
