calc_km_pi: Generate Kaplan-Meier curves with prediction intervals from parametric bootstrap simulation

Description

Generate Kaplan-Meier curves with prediction intervals from parametric bootstrap simulation

Usage

calc_km_pi(
  sim,
  trt = NULL,
  group = NULL,
  pi.range = 0.95,
  calc.obs = TRUE,
  simtimelast = NULL
)

Arguments

sim

A survparamsim class object generated by surv_param_sim function.

trt

An optional string to specify which column define treatment status. You will have survival curves with different colors in plot_km_pi function.

group

Optional string(s) to specify grouping variable(s). You will have faceted survival curves for these variables in plot_km_pi function.

pi.range

Prediction interval for simulated survival curves.

calc.obs

A logical to specify whether KM estimates will be performed for the observed data. Need be set as FALSE if survival information in the newdata is dummy.

simtimelast

An optional numeric to specify last simulation time for survival curve. If NULL (default), the last observation time in the newdata will be used.
