Description: 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)
