Description: Fit penalized splines mixed-effects models (a special case
        of additive models) for large longitudinal datasets. The
        package includes a psme() function that (1) relies on package
        'mgcv' for constructing population and subject smooth functions
        as penalized splines, (2) transforms the constructed additive
        model to a linear mixed-effects model, (3) exploits package
        'lme4' for model estimation and (4) backtransforms the
        estimated linear mixed-effects model to the additive model for
        interpretation and visualizaiton. See Pedersen et al. (2019)
        <doi:10.7717/peerj.6876> and Bates et al. (2015)
        <doi:10.18637/jss.v067.i01> for an introduction. Unlike the
        gamm() function in 'mgcv', the psme() function is fast and
        memory-efficient, able to handle datasets with millions of
        observations.
