Wolfgang ViechtbauerTogether with colleagues from Spain, we recently conducted a comprehensive simulation study examining the performance of various types of tests and methods for constructing confidence intervals for the scale coefficients in meta-analytic location-scale models. Although things are complex, generally the likelihood-ratio test and corresponding profile-likelihood intervals performed best.

Wolfgang Viechtbauer1/3 In a recent paper, we described the use of location-scale models in meta-analysis to not only examine how moderators may be related to the size of the effect, but also how moderators may be related to the amount of heterogeneity among the effects: <a href="https://doi.org/10.1002/jrsm.1562" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://doi.org/10.1002/jrsm.1562</a>Such models can be fit with the metafor package in R: <a href="https://wviechtb.github.io/metafor/reference/rma.uni.html#location-scale-models" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://wviechtb.github.io/metafor/reference/rma.uni.html#location-scale-models</a><a href="https://scholar.social/tags/statistics" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#statistics</a> <a href="https://scholar.social/tags/MetaAnalysis" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#MetaAnalysis</a> <a href="https://scholar.social/tags/EvidenceSynthesis" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#EvidenceSynthesis</a> <a href="https://scholar.social/tags/ResearchSynthesis" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#ResearchSynthesis</a> <a href="https://scholar.social/tags/Rstats" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Rstats</a>

Wolfgang ViechtbauerNice to see Georgia Salanti (<a href="https://mastodon.social/@geointheworld" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@geointheworld</a>) joining Mastodon.

Jürgen Schneider<a href="https://scicomm.xyz/tags/ResearchSynthesis" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#ResearchSynthesis</a> folks! I created an R script to scrape <a href="https://scicomm.xyz/tags/googleScholar" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#googleScholar</a> search results to save you (and me) the tedious clicking. Put in your search string and number of search results you need and get a csv.
