SimGSB

Verifies the results of <code>GrpSeqBnds</code> via simulation

misc

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>.

<dl> <dt>object</dt>
<dd>an object of class either <code>boundaries</code> or <code>PwrGSD</code></dd> <dt>nsim</dt>
<dd>number of simulations to do</dd> <dt>...</dt>
<dd>if <code>object</code> is of class <code>PwrGSD</code> and there are
 more than one statistic under investigation, then you may specify an
 argument <code>stat</code>. The default value is 1, meaning the first one.</dd></dl>
