drmeta: Design-Indexed Location-Scale Meta-Analysis
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. A grouped scale
diagnostic checks whether a monotone curve misses an interior peak or
trough. 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.
