Confidence Bands for the Median Survival Time as a Function of the Covariates in the Cox Model
Abstract
The proportional hazards model of Cox (1972) specifies that the hazard rate for an individual with covariate vector x is a certain equation where beta sub o is a vector of unknown-regression coefficients and lambda, the underlying baseline hazard rate, is an unknown and unspecified nonnegative function. In most cases where this model is used, interest centers on the estimation of beta sub o. However, it is often also very useful to investigate the effect of the covariates on the median (or some other fixed quantile) of the survival time.
