     The package provides tests for comparing two survival
     distributions, testing equality of two cumulative incidence
     functions under competing risks and checking goodness of fit of
     proportional rate models (proportional hazards, proportional odds)
     for two samples.

       Package:  surv2sample
       Type:     Package
       Version:  0.1-0
       Date:     2007-11-08
       License:  GPL 2 or newer

     The package implements many two-sample tests for right-censored
     survival data. Three main areas and corresponding methods are:

        *  comparison of two survival distributions

           *  'surv2.logrank': weighted logrank tests and their
              combinations (max, sum)

           *  'surv2.neyman': Neyman's smooth test and its data-driven
              version

           *  'surv2.ks': Kolmogorov-Smirnov, Cramer-von Mises and
              Anderson-Darling test

        *  comparison of two cumulative incidence functions for
           competing risks data

           *  'cif': estimation and plotting of cumulative incidence
              functions

           *  'cif2.logrank': logrank-type test for subdistribution
              hazards

           *  'cif2.neyman': Neyman's smooth test and its data-driven
              version

           *  'cif2.ks': Kolmogorov-Smirnov test

           *  'cif2.int': integrated-difference test

        *  goodness of fit tests of the proportional rate assumption
           (proportional hazards or proportional odds functions in two
           samples)

           *  'proprate2': estimation based on the simplified partial
              likelihood

           *  'proprate2.ks': Kolmogorov-Smirnov test

           *  'proprate2.neyman': Neyman's smooth test and its
              data-driven version

           *  'proprate2.gs': Gill-Schumacher type test

     The package also provides three datasets:

        *  'gastric': gastric cancer data

        *  'bmt1': bone marrow transplant data

        *  'hepatitis': chronic active hepatitis data
