metaSEM: An R Package for Meta-Analysis using Structural Equation Modeling Mike W.-L. Cheung National University of Singapore 1 May 2013 Abstract The metaSEM package provides functions to conducting univariate and multivariate meta-analysis using a structural equation modeling (SEM) approach via the OpenMx package.

Nov 15, 2017  · The default is a random effects analysis with a restricted maximum likelihood estimator (REML). “Study labels”, which allows you to associate a text label with each of the studies. “Covariates” in which you insert any numerical covariates to be included in a meta-regression.

Mar 26, 2019  · Subject: Re: REML meta-analysis Fellow Genstatters I would like some advice on partitioning an ANOVA table into certain contrasts.
