Power when a squared term is omitted for 0, 25, and 50% censoring rates. The RC statistic was calculated for the full (y~ x₁ and x₁²) and reduced (y~ x₁) models. Data were simulated according to the full model, but the reduced model was used to estimate the expected proportions in the RC statistic formula. Left panel—decreasing baseline hazard, right panel—increasing baseline hazard. N = 1000 (top row), 5000 (middle row), 10,000 (bottom row), p = 0.1, collapse when ev_g < 5
