Parameter Description: Type Of Shape

internal

Design and analysis of confirmatory adaptive clinical trials with continuous, binary, and survival endpoints according to the methods described in the monograph by Wassmer and Brannath (2016) <doi:10.1007/978-3-319-32562-0>. This includes classical group sequential as well as multi-stage adaptive hypotheses tests that are based on the combination testing principle.

param_typeOfShapeRates function

<dl><dt>typeOfShape</dt>
<dd>The shape of the dose-response relationship over the treatment groups.
This can be either <code>"linear"</code>, <code>"sigmoidEmax"</code>, or <code>"userDefined"</code>,
default is <code>"linear"</code>. 
For <code>"linear"</code>, <code>piMaxVector</code> specifies the range
of effect sizes for the treatment group with highest response.
If <code>"sigmoidEmax"</code> is selected, <code>gED50</code> and <code>slope</code> has to be entered
to specify the ED50 and the slope of the sigmoid Emax model.
For <code>"sigmoidEmax"</code>, <code>piMaxVector</code> specifies the range
of effect sizes for the treatment group with response according to infinite dose.
If <code>"userDefined"</code> is selected, <code>effectMatrix</code> has to be entered.</dd></dl>
