Empirical size and power of the tests in scenario 2. Empirical size (α) and power (1 - β) of the tests for CD and NCD in scenario 2 (HR
CD = 1, HR
NCD = 1.25). The data are simulated without censored observations. The plots on the first line concern CD, those on the second line NCD. The plots on the left are for data with correct causes of death (P(misclass) = 0%), those on the right for data with 20% of misclassified causes of death (P(misclass) = 20%). The bold grey horizontal line corresponds to the 0.05 level and ρ to the correlation.
