Simulation-based distributions of odds ratio estimates using RFPM and logistic regression. Simulated distributions of the conditional odds ratios for X 1 , X 2 , and X 3 under Model 1 (3 main effects) estimated using a main effects logistic regression model (LR1), a logistic regression model with main effects and all two-way interactions (LR2) and a risk machine using RFPM and the “two-machine method”. The solid lines represent the true main effects present in the data.
