A class of tests for homogeneity of quantiles under unequal right-censorship

A class of tests is considered for testing equality of quantiles (of a specified order) of K ([greater-or-equal, slanted] 2) continuous populations when the observations are subject to random right-censorship. The tests may be viewed as a generalization of a class of tests considered by Sen (1962) to the case of right-censored data. The proposed tests are useful when the censoring distributions are unequal and do not require the scale or the shape parameters of the underlying populations to be either known or equal.
