Compute bootstrap variance of the log hazard ratio — get_boot_var_se • ipcw

Compute bootstrap variance of the log hazard ratio

Usage

get_boot_var_se(data, B)

Arguments

data: A data frame with a column log_hr containing bootstrap log hazard ratio estimates, as returned by multiple calls to get_ipcw_cox_fit_se() or get_cox_fit_se().
B: Integer. Number of bootstrap samples used.

Value

A single numeric value: the bootstrap variance estimate.

Examples

# Toy example with 10 simulated bootstrap log HRs
boot_results <- data.frame(log_hr = rnorm(10, mean = -0.5, sd = 0.2))
get_boot_var_se(boot_results, B = 10)
