longpower: Sample Size Calculations for Longitudinal Data (original) (raw)
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) ISBN:9780199676750, and Lu, Luo, and Chen (2008) <doi:10.2202/1557-4679.1098>.
