Sample Size Calculations for Longitudinal Data

Installation

About

Compute power and sample size for linear models of longitudinal data. Supported models include mixed-effects models and models fit by generalized least squares and generalized estimating equations. The package is described in Iddi and Donohue (2022) doi:10.32614/RJ-2022-022. Relevant formulas are derived by Liu and Liang (1997) doi:10.2307/2533554, Diggle et al (2002) , and Lu, Luo, and Chen (2008) doi:10.2202/1557-4679.1098.
