| Abstract: | In 1983, Kitchin, Langberg and Proschan introduced a piecewise exponential estimator (PEXE) of a survival function for censored data that is undefined beyond the last observation. We propose a new PEXE that provides an exponential tail with a hazard rate determined by a novel nonparametric consideration. |
