A Study on the Median and Quantile residual lifetime for left truncated and right censored data Farzad Ramideh f ramideh@math iut ac ir 2017 Department of Mathematical Sciences Isfahan University of Technology Isfahan 84156 83111 Iran Supervisor Dr Sareh Goliforushani s goli@cc iut ac ir Advisor Dr Zahra Saberi z saberi@cc iut ac ir 2010 MSC 05C15 53C42 Keywords median and quantile residual lifetime pointwise confdence interval Gastric cancerdata left truncated and right censored data AbstractIn recent years interest has grown in the study of the residual lifetime Residual lifetime at time tis defined as the remaining lifetime of a subject or a unit who has already survived at least t Thisconcept is widely used in many technical systems and life analyses For example in medicine thepatients especially those who suffer from a chronic disease like cancer are interested in knowing theirremaining lifetime Besides in a randomized Phase III breast cancer clinical trial the physician needsto use the obtained residual life to advise whether a patient should participate in the study to takea different type of therapy Residual lifetime function also has a tremendous range of applications inmany other studies such as to model the duration of strikes length of wars job mobility in socialscience and analysis in the recidivism The mean residual life function and the median residual life function and the quantile residual lifefunction are three types of measurements which have been studied by several authors In recent years an empirical estimator for mean residual life function based on order statistics obtained and presented a large number of cases for mean residual life in sociological applications During the research on the properties of mean residual life function we know that the mean residuallife function does not always exist when the distribution is heavy tailed thus we can use the median
