Quantile regression of right-censored length-biased data using the Buckley–James-type method

Cheng, Jung-Yu; Tzeng, Shinn-Jia - In: Computational Statistics 29 (2014) 6, pp. 1571-1592

Length-biased data are encountered frequently due to prevalent cohort sampling in follow-up studies. Quantile regression provides great flexibility for assessing covariate effects on survival time, and is a useful alternative to Cox’s proportional hazards model and the accelerated failure time...

Simulations on the Theil-Sen regression estimator with right-censored data

Wilcox, Rand R. - In: Statistics & Probability Letters 39 (1998) 1, pp. 43-47

modified Buckley-James estimator never offers an advantage when there is 20% or 50% censoring. …This note compares the small-sample efficiency of the extended Theil-Sen estimator to the modified Buckley-James … estimator when the predictor is random. Included are situations where the error term is heteroscedastic. In terms of their …
