Abstract:
|
We adjusted multi-sample U-statistics for comparison group distributions with right censored and confounding covariates by inverse probability of censoring weighting and score adjustment. The group membership, outcome and censoring may depend on the covariates. Simulation results used to illustrate the performances of our U-statistics. In addition, Jackknife variance estimations were obtained and compared to the empirical values. A real data set on Bone Marrow transplant for Leukemia was applied to exemplify its usefulness.
