setup_cpp: Set Up Calibrated Power Prior Design Object

In basksim: Simulation-Based Calculation of Basket Trial Operating Characteristics

Set Up Calibrated Power Prior Design Object

Description

Set Up 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
