Generate Kaplan-Meier curves with prediction intervals from parametric bootstrap simulation
calc_km_pi(
sim,
trt = NULL,
group = NULL,
pi.range = 0.95,
calc.obs = TRUE,
simtimelast = NULL
)
A survparamsim
class object generated by surv_param_sim
function.
An optional string to specify which column define treatment status.
You will have survival curves with different colors in plot_km_pi
function.
Optional string(s) to specify grouping variable(s).
You will have faceted survival curves for these variables in plot_km_pi
function.
Prediction interval for simulated survival curves.
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.
An optional numeric to specify last simulation time for survival curve.
If NULL (default), the last observation time in the newdata
will be used.
