Please bear with me, I am very new to R. My question is regarding the use of the improveProb function in the Hmisc package. I have two logistic models, the only difference being that the second model contains my novel marker of interest. I am trying to calculate NRI and IDI to compare models.
I have the PredRisks for both models - PredRisk1 and PredRisk2, and my outcome is disease 0/1. How do I define this in R in order to run improveProb(x1, x2, y)?
