Setup Calibrated Power Prior Design Object

Description

Setup Calibrated Power Prior Design Object

Usage

setup_cpp(k, p0, shape1 = 1, shape2 = 1)

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 cpp 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 baskets (which is equivalent to the absolut difference in response rates).

Value

An S3 object of class cpp
