Hazard ratio between two groups via a simple Cox model.
Usage
morie_survival_hr(time, event, group, confidence = 0.95)
Arguments
- time
Numeric vector of event/censoring times.
- event
Integer/logical vector; 1 = event, 0 = censored.
- group
Factor/character grouping variable for HR / log-rank
stratified comparisons.
- confidence
Confidence level for interval estimates (default
0.95).
Value
A named list with elements hr, ci_lower, ci_upper, p_value, log_hr, se.
Examples
set.seed(1)
time <- rexp(60); event <- rbinom(60, 1, 0.7)
group <- rep(c(0, 1), 30)
str(morie_survival_hr(time, event, group), max.level = 1)
#> List of 6
#> $ hr : num 0.799
#> $ ci_lower: num 0.445
#> $ ci_upper: num 1.43
#> $ p_value : num 0.451
#> $ log_hr : num -0.225
#> $ se : num 0.298
