Description: Fuzzy survival analysis for data in which event times
        and/or failure indicators are vague, for instance when a
        failure is only known to have occurred during the second
        quarter of a year, or when it is uncertain whether a subject
        lost to follow-up had in fact failed.  Vague information is
        represented by fuzzy numbers.  The package provides a fuzzy
        product-limit estimator obtained from nested alpha-cuts of the
        fuzzy survival function, a fuzzy Cox proportional hazards model
        with fuzzy coefficient and hazard ratio estimates, and a fuzzy
        log-rank test. Type-reduction utilities for summarizing fuzzy
        estimates by single numbers, a simulation engine for validation
        studies, plotting, print and summary methods, and alpha-cut
        based confidence bands are provided.  The bounds are computed
        at the alpha-cuts of the fuzzy event times, so the alpha-cut
        intervals returned for the survival function, the regression
        coefficients and the test statistic are nested by construction.
