death
In this section, we give results when estimation is based on Cox's proportional hazards model. In a small proportion of simulated trials, there was no convergence while computing Simulated biases and root mean squared errors for the various estimators for the log hazard ratiosSmallest bias in bold.Smallest Root mean squared error in bold.Four scenarios based on different values for the true log HRs vector Boxplots for treatment four log hazard ratio estimates for (A‐D) scenarios 1 to 4. The true log hazard ratios are represented by the dashed and dotted linesFor Scenario 2, The third scenario considers a case where the four treatments have distinct hazards of death (Scenario 4 (
