title: Rank analysis of covariance with right-censored data.
abstract: A modification of the rank analysis of covariance, suitable for randomly right-censored dependent variate observations, is proposed and studied. The test suggested is based on an appropriate permutation distribution of the rank scores, and for large samples may be conducted by using the chi square distribution. The principal assumptions are that both censoring and covariate distributions do not depend on the treatment group.
