The survival data are often censored in nature and hence semi-parametric or nonparametric methods are mostly used for estimating the survival or hazard functions and also for making other types of analysis. It is to be noted that the life-times of several natural phenomena are continuous in nature, not the precise numbers and hence denoting the life-times as precise may be absurd. Viertl (2009) has shown that life times are more or less fuzzy. In this research paper, a procedure for Generalized Nelson-Aalen Estimator is introduced on the basis of fuzzy survival times. Examples are given to substantiate the proposed method.
