Effective Information for Survival (Cox PH)

Computes \(d_{\text{eff}} = n_H (1 - p_c)\) where \(p_c\) is the censoring proportion.

Usage

d_eff_survival(n_sg, prop_cens)

Arguments

n_sg

Integer. Subgroup sample size.

prop_cens

Numeric. Proportion censored (0–1).

Value

Numeric. Effective information (expected events).

Examples

d_eff_survival(n_sg = 60, prop_cens = 0.45)
