The methodology is generalized to … Webb30 jan. 1996 · Brookmeyer and Crowley derived a non-parametric confidence interval for the median survival time of a homogeneous population by inverting a generalization of the sign test for censored data. The 1−α confidence interval for the median is essentially the set of all values t such that the Kaplan–Meier estimate of the survival function at time t …
