plot {anoint} | R Documentation |
Prognostic response plot (PR-plot) for anoint
class.
Description
Computes the prognostic score (baseline risk) based on the covariates of anoint
or a supplied set of predictions. Risk scores are binned into ten groups based on risk deciles and a treatment effect (and confidence interval) is estimated in each group. This is compared to the overall treatment effect which is indicated by the shaded region.
Details
Additional arguments are passed to glm
or coxph
.
Methods
- plot
signature(object = "anoint",predict=NULL,fun=exp,...)
: Prognostic response plot.
