setup_cppglobal: Setup Global Calibrated Power Prior Design Object
Description
Setup Global Calibrated Power Prior Design Object
Usage
setup_cppglobal(k, p0, shape1 = 1, shape2 = 1)
Value
An S3 object of class cppglobal
Arguments
k
The number of baskets.
p0
A common probability under the null hypothesis.
shape1
First common shape parameter of the beta prior.
shape2
Second common shape parameter of the beta prior.
Details
The class cppglobal implements a version of the power prior
design, in which the amount of information that is shared between baskets is
determined by the Kolmogorov-Smirnov test statistic between basekts and
a function based on response rate differences that quantifies the
overall heterogeneity.
