boot_hr: Bootstrap hazards ratios of two survival models 'boot_hr'...

In DARTH-git/darthtools: darthtools is an R package that contains tools developed by the Decision Analysis in R for Technologies in Health (DARTH) workgroup to construct model-based cost-effectiveness analysis in R.

Bootstrap hazards ratios of two survival models boot_hr computes bootstrap hazard ratios (HR) of two survival models (model 1 vs. 2) or one survival model with multiple treatments (rx 1 vs. 2)

Description

Bootstrap hazards ratios of two survival models boot_hr computes bootstrap hazard ratios (HR) of two survival models (model 1 vs. 2) or one survival model with multiple treatments (rx 1 vs. 2)

Usage

boot_hr(
  surv_model1 = NULL,
  surv_model2 = NULL,
  rx1 = NULL,
  rx2 = NULL,
  rx = F,
  surv_model_rx = NULL,
  times,
  B = 100
)

Arguments

surv_model1	first survival model.
surv_model2	second survival model.
rx1	first treatment arm (if rx = T).
rx2	second treatment arm (if rx = T).
rx	whether to model treatment arms within one model. Default = FALSE.
surv_model_rx	survival model (if rx = T), can only choose weibull or gamma models.
times	time horizon the extrapolation of the survival model is done over.
B	number of bootstrap samples.

Value

dataframe of hazard ratio statistics (2.5% percnetile, median, 97.5% percentile, time points)
