Description: This package contains functions to assess the
        time-dependant ROC curve for a prognostic marker from
        aggregated data (survival probabilities in strata of the
        marker) and from several studies. The hazard function
        associated with the time-to-event is modeled as a piecewise
        constant function, and the package proposes 2 functions
        corresponding respectively to a 4-piece and a 5-piece constant
        functions. The area under the summary time-dependant ROC
        (SROCt) curve is assessed by using the trapezoidal rules.
