Mike Cheung replied to Nina Lasek's discussion Meta-analysis & moderated mediation? in the group Meta-analytic structural equation modeling

"Dear Nina, I would only consider MASEM or meta-analysis on the moderated mediated effects when the raw data are not available. If you have the raw data, I think that the multiple-group SEM approach is more easier. Best, Mike"

Mike Cheung replied to saneesh edacherian's discussion Interaction effects through Meta-analysis in the group Meta-analytic structural equation modeling

"The correlation matrix of A, B, C, and D does not include any information on the moderating effect. Unless you have the product terms, I do not think that it is possible to test the moderation effect."

Mike Cheung commented on Mike Cheung's group Meta-analytic structural equation modeling

"Dear Nina, If the data (scales) are comparable across studies, I would suggest using either a multiple-group SEM (fixed-effects model) or a multilevel SEM (random-effects model) in Mplus. MASEM or using the moderated mediation as the effect size…"

Mike Cheung commented on Mike Cheung's group Meta-analytic structural equation modeling

"Dear Empi, There is no grouping variable because the data are summary statistics (correlation matrices). test.cov may include the stacked correlation matrices, e.g., 1 .2 1 .3 .4 1 1 .3 1 .4 .5 1 The sample sizes are specified by NOBSERVATIONS = 100…"

Empi commented on Mike Cheung's group Meta-analytic structural equation modeling

"Dear Mike et al., this post http://www.statmodel.com/discussion/messages/11/3993.html shows how to use Mplus for pooling correlation matrices. However, I wonder why there is no need to indicate the sample/group the original data refer…"

Mike Cheung replied to Empi's discussion MASEM for individual-level survey data? in the group Meta-analytic structural equation modeling

"Dear Empi, I did not suggest conducting a meta-analysis with the multiple-group analysis though it is possible. You mentioned that you have the raw data. That's why I suggested that there are several possible ways to analyze the data including…"

Mike Cheung replied to Empi's discussion MASEM for individual-level survey data? in the group Meta-analytic structural equation modeling

"Hi Empi, The WLS estimation in Mplus is meant for covariance matrices. It will not work for correlation matrices which are usually required for MASEM. Best,Mike"

Mike Cheung replied to Empi's discussion MASEM for individual-level survey data? in the group Meta-analytic structural equation modeling

"Dear Empi, Since you have the raw data, there are several options for you. You may either conduct a multilevel or multiple-group structural equation modeling (see Mplus's manual). Alternatively, you may run either a correlation- or…"
