longpower

longpower-package

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) tools:::Rd_expr_doi("10.32614/RJ-2022-022"). Relevant formulas are derived by Liu and Liang (1997) tools:::Rd_expr_doi("10.2307/2533554"), Diggle et al (2002) &lt;ISBN:9780199676750&gt;, and Lu, Luo, and Chen (2008) tools:::Rd_expr_doi("10.2202/1557-4679.1098").
