CDFOR2LRR

Given the values of the baseline hazard and odds ratio of the CDF at
 a grid of time points find the corresponding logged risk ratio.

Tools for the evaluation of interim analysis plans for sequentially
monitored trials on a survival endpoint; tools to construct efficacy and
futility boundaries, for deriving power of a sequential design at a specified
alternative, template for evaluating the performance of candidate plans at a
set of time varying alternatives. See Izmirlian, G. (2014) <doi:10.4310/SII.2014.v7.n1.a4>.
