lung

<p>Survival in patients with lung cancer at Mayo
     Clinic. Performance scores rate how well the patient can perform
     usual daily activities.</p>

datasets

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>.
