A Fuzzy Approach to Kaplan-Meier Estimator

Abstract

The application of the concept of fuzziness to statistical data is always meaningful because of the fact that data are imprecise in general. In survival analysis, the lifetimes which are continuous in nature or not precise numbers, and hence they are more or less fuzzy (Viertl (2009)). In this article, a procedure for the Kaplan-Meier estimator has been proposed by considering fuzzy survival times. The results obtained are substantiated through examples.
