Description: Fits constrained and unrestricted meta-analytic location-scale
    models in which residual between-study heterogeneity is modeled as an
    exponential function of a prespecified design-robustness score. The
    package supports maximum-likelihood (ML) and restricted
    maximum-likelihood (REML) estimation, location moderators, the
    conventional random-effects model as a nested special case, exact
    estimation at the nonnegative scale-gradient boundary, design-indexed
    heterogeneity summaries, scale-attenuation measures, prediction of
    fitted heterogeneity, leave-one-out influence diagnostics, and
    parametric-bootstrap inference for the scale gradient. Because the
    scale-gradient null lies on the boundary of the constrained parameter
    space, standard chi-square likelihood-ratio references do not apply
    (Self and Liang, 1987, <doi:10.1080/01621459.1987.10478472>). The
    general location-scale parent model is described in Viechtbauer and
    Lopez-Lopez (2022, <doi:10.1002/jrsm.1562>). A scale model reweights
    studies and does not adjust the mean for design-linked bias.
