Hi everyone - Thank you for all your guidance in advance! I have a couple of questions -- (1) is there a way to correct for range restriction and/or measurement error in multilevel analyses and (2) is there a way to...

Hi folks, I'm curious if there is a specific threshold for effect sizes to be considered influential and/or outlier cases using Cook's Distance, Hat Values, and DF Betas measures. I've seen examples of this done for...

Hi folks, Thanks for all your help! I was curious if there is a way to get the variance composition of a moderator analysis across the different categorical levels? For example, I have a three-level meta-analysis with publication...

Hello Listserv - I wanted to know if folks know of a way to get prediction intervals for moderator analyses! I tried the predict() function but the output looks incorrect. I attached a screenshot below of the code plus a part...

I was asked by reviewers to conduct a Pet-Peese analysis for publication bias, but I'm not sure how to conduct a Pet-Peese analysis on a rma.mv object in metafor. (1) Does anyone know if it is...

Hello, Thank you again for all your guidance. I have been trying to conduct PET-PEESE analyses on several rma.mv objects by adding variance as a moderator. The following code works well: #pet-peese test m_1_pet <- rma...

Hello Listserv - I hope this note finds you well. I am working on a multilevel meta-analysis and a reviewer asked us to correct for statistical artifacts (e.g., measurement error). The reviewer cited Wiernik & Dahlke (2020) which includes some...

Hello Listserv - I'm sending this question out again in case it slipped through the cracks: I am working on a multilevel meta-analysis and a reviewer asked us to correct for statistical artifacts (e.g., measurement error). The reviewer...

Hello, Thank you all in advance for your help. I had two minor issues with my rma.mv models that I wanted to consult with you. The first issue is that I am trying to plot regression plots of moderator...

Hi Michael, Thanks for your response! What do you mean by profiling the variance? Yes, some of my moderators had virtually no effect in our models. I have the issue with the PI being displayed for each data point in...

Thanks, all! Unfortunately, the profile() function did not yield PIs for our moderator analyses. Are there other ways to get the PIs for rma.mv models since predict() and profile() are not working? On Thu, Jun 15, 2023 at 12...

Hi Wolfgang, Thank you for clarifying! I apologize for the misunderstanding. I'm trying to use the newmods argument just now but am still confused. I tried entering the moderator name which did not work. I also checked the website...

Hi folks, I wanted to follow-up this question and ask if there is a way (or is it recommended) to generate a color-enhanced funnel plot on a rma.mv object? Thanks in advance! On Tue, May 24, 2022...

Hi again, I just wanted to follow-up on this email - I am running a three-level rma.mv model in R. When I calculated I^2, it suggested that 78% of heterogeneity is *within *clusters in level two. I...
