risks

Risk ratios and risk differences are estimated using regression models that allow for binary, categorical, and continuous exposures and confounders. Implemented are marginal standardization after fitting logistic models (g-computation) with delta-method and bootstrap standard errors, Miettinen's case-duplication approach (Schouten et al. 1993, doi:10.1002/sim.4780121808), log-binomial (Poisson) models with empirical variance (Zou 2004, doi:10.1093/aje/kwh090), binomial models with starting values from Poisson models (Spiegelman and Hertzmark 2005, doi:10.1093/aje/kwi188), and others.
