Comparison of quantile regression curves with censored data

This paper proposes a new test for the comparison of conditional quantile curves when outcome interest, typically duration, is subject to right censoring. The can be applied both in case two independent samples and paired data, used quantiles at fixed level, finite set levels or range levels. asymptotic distribution proposed statistics obtained under null hypothesis local alternatives. We describe bootstrap procedure order approximate critical values present results simulation study, which performance tests small moderate sample sizes studied compared with behavior alternative tests. Finally, we apply on data concerning diabetic retinopathy.
