To estimate the relative risk directly, binomial regression and Poisson regression are usually recommended. However, as is commonly known, neither works very well. Binomial regression models may suffer convergence problems and fail to provide a valid estimate of relative risk.

WebSep 13, 2011 · Abstract. Relative risks (RRs) are generally considered preferable to odds ratios in prospective studies. However, unlike logistic regression for odds ratios, the standard log-binomial model for RR regression does not respect the natural parameter constraints and is therefore often subject to numerical instability.
