Calculate Power and Sample Size with Beta Regression
Description
Power calculations are a critical component of any research study to determine the
minimum sample size necessary to detect differences between multiple groups.
Researchers often work with data taking the form of proportions that can be modeled with
a beta distribution. Here we present an R package, 'BetaPASS', that perform power and
sample size calculations for data following a beta distribution with comparative
nonparametric output. This package allows flexibility with multiple options for link
functions to fit the data and graphing functionality for visual comparisons.
