data2_ushape

A dataset containing data for testing the ushape argument of cp_est function.

datasets

Estimate one or two cutpoints of a metric or ordinal-scaled
variable in the multivariable context of survival data or
time-to-event data. Visualise the cutpoint estimation process using contour
plots, index plots, and spline plots. It is also possible to estimate
cutpoints based on the assumption of a U-shaped or inverted U-shaped
relationship between the predictor and the hazard ratio.
