WebJul 10, 2024 · I want to update the model by adjusting baseline risk only, so I have been using a Cox model with the linear predictor ("beta.sum") included as an offset term, to restrict its coefficient to be 1. I want to be able to use cph instead of coxph as it makes internal validation by bootstrapping much easier. However, when including the linear ... WebSecond, use plot () instead of plot.Predict to save work. Third you can easily generate plots for both sexes, e.g. using Predict (fit, age, sex, fun=exp) # exp=anti-log; then plot (result) or plot (result, ~ age sex). You don't use "x=NA" in Predict. rms uses lattice graphics so usual par graphics parameters and mfrow don't apply.
