Description: Provides analytic derivatives and information matrices for
        fitted linear mixed effects (lme) models and generalized least
        squares (gls) models estimated using lme() (from package
        'nlme') and gls() (from package 'nlme'), respectively. The
        package includes functions for estimating the sampling
        variance-covariance of variance component parameters using the
        inverse Fisher information. The variance components include the
        parameters of the random effects structure (for lme models),
        the variance structure, and the correlation structure. The
        expected and average forms of the Fisher information matrix are
        used in the calculations, and models estimated by full maximum
        likelihood or restricted maximum likelihood are supported. The
        package also includes a function for estimating standardized
        mean difference effect sizes (Pustejovsky, Hedges, and Shadish
        (2014) <DOI:10.3102/1076998614547577>) based on fitted lme or
        gls models.
