Table 3.

Empirical rejection rates for Experiment 1 and 2. Test of F₁ (t) = F₂ (t) over the entire time range was performed using a permutation test with 1000 permutations. Results based on 1000 simulations (for test under H₀) and 200 simulations (for test under H₁), with sample size n = 500 and 40% censoring (under H₁).
