This model form dialog box is accessed through the model specification dialog. It can be used to set the form of the model. The default model is an additive excess relative risk (ERR) model. This model includes the usual log-linear multiplicative relative risk model as a special case, but also allows one to model excess relative risks with multiplicative effect modification. The additive model, in which risks are described as a sum of, possibly nonlinear, subterms is useful for modeling excess rates. Additional details are in The EPICURE Regression Programs section of the Epicure User Guide. .
