Generate hazard ratio with prediction intervals from parametric bootstrap simulation
calc_hr_pi(
sim,
trt,
group = NULL,
pi.range = 0.95,
calc.obs = TRUE,
trt.assign = c("default", "reverse")
)
A `survparamsim` class object generated by surv_param_sim
function.
A string to specify which column define treatment status to calculate HR. The specified column should have only two levels.
Optional string(s) to specify grouping variable(s).
You will have faceted histograms for these variables in plot_hr_pi
function.
Prediction interval for simulated HR.
A logical to specify whether to calculate HR for the observed data. Need be set as FALSE if survival information in the `newdata`` is dummy.
Specify which of the categories of `trt` need to be considered as control group.
