Description: Computes model-based effect sizes for fixed-effect coefficients
    in multilevel (hierarchical) models. The coefficient effect sizes are
    standardized mean differences from zero (d) and unique variance-explained
    measures (squared semi-partial correlations, sr2). The package also reports
    variance components and level-specific and total R-squared values. It
    supports 2-level and 3-level linear and binary logistic models fitted with
    'lme4' (Bates et al., 2015) <doi:10.18637/jss.v067.i01>, and 2-level
    Gaussian and Bernoulli models fitted with 'brms' (Bürkner, 2017)
    <doi:10.18637/jss.v080.i01>. Sanders, Konold, and Cheng (in press),
    "Model-based effect sizes for multilevel linear regression coefficients,"
    Methodology: European Journal of Research Methods for the Behavioral and
    Social Sciences, describe the 2-level linear-model methods.
