In the thesis, we review important literature on quantile regression models for survival data. First, we introduce the inference techniques for estimating a quantile based on complete data without covariates. This allows us to see the geometric structure and analytical difficulty of the problem. Then we include the effect of covariates and discuss different estimation procedures. Geometric explanations are also provided. Finally the effect of censoring is incorporated and we discuss several approaches of modification. We aim to provide a systematic framework which allows the readers to understand the quantile regression model from fundamental inference principles.
