Estimation of adjusted relative risks in log-binomial regression using the Bekhit–Schöpe–Wagenpfeil algorithm
-
Stefan Wagenpfeil
Abstract
Classical log-binomial regression is a prominent statistical model for adjusted relative risk estimation in the framework of prospective, observational studies. However, there was and still is an already long-lasting debate on workarounds due to problems and sometimes failed convergence of respective maximum likelihood estimation (MLE) of model parameters, i. e., regression constant as well as covariate effects. We describe two areas of problems that can be seen as essential sources for nonconvergence issues in the specific class of regression models. In order to overcome the problems, a new and direct approach for MLE in log-binomial regression, called BSW, is presented. The implementation of BSW can either be seen as generalization of the classical Newton method for nonlinear programming without constraints to the further case of linear inequalities. On the other hand, one can simplify a classical sequential quadratic programming (SQP) algorithm allowing for nonlinear equalities and inequalities to the specific case of linear inequality constraints analogously, and obtain the same algorithmic approach, which we call BSW. Furthermore, convergence issues considering local and global convergence as well as convergence speed are discussed and referenced also. For algorithmic application, we present essential results summarizing large simulation studies on the one hand, and give reference to a real data example on the other. Exemplary visualization of the iterative steps of BSW is also given, and implementation of BSW can be found as an R package on CRAN.
