  1. aTrue beta obtained from the application of every model on the renal transplant dataset.
  2. bMean difference and mean squared difference represent respectively the average deviation and its square of every bootstrap estimate from the true value beta.
  3. cMean difference and mean squared difference should be multiplied by the number specified next to the outcome name.
  4. dSPRI model has best results compared to other models: 50% of the estimates have smallest mean difference and mean squared difference under SPRI.
