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.
