Power and Sample Size Calculations with Hierarchical Endpoints
Description
Calculate sample size or power for hierarchical endpoints.
The package can handle any type of outcomes (binary, continuous, count, ordinal,
time-to-event) and any number of such endpoints. It allows users to calculate
sample size with a given power or to calculate power with a given sample size
for hypothesis testing based on win ratios, win odds, net benefit, or DOOR
(desirability of outcome ranking) as treatment effect between two groups for
hierarchical endpoints. The methods of this package are described further in
the paper by Barnhart, H. X. et al. (2024, ).
