“…Methods used to detect asymmetry and publication bias are routinely employed in meta-analyses of group-design research. Although used less often in behavior analysis research compared to other fields, these methods are used in metaanalyses of behavioral research (see e.g., Amlung et al, 2016;McCormack et al, 2019) and meta-analyses of SCED studies (see e.g., Babb et al, 2020;Bowman-Perrot et al, 2014;Garwood et al, 2021;Shin et al, 2020). When attempting to aggregate behavior science research using frequentist statistical analysis, heterogeneity should be accounted for in the model minimally at the participant level (level 1) and the study level (level 2), referred to as a multilevellevel model meta-analysis (Becraft et al, 2020;Moeyaert et al, 2020).…”
