title: 'fuzzySurvival: Fuzzy Survival Analysis with Vague Event Times and Fuzzy Censoring'
version: 0.1.0
abstract: 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.
