survParamSim (version 0.1.0)

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.
