[R-meta] multi-level random effects meta-analysis: valid funnel plot & Egger's test?

[Mark Assink]

Dear Jennifer,

In addition to Wolfgang's tips, you may want to have a look at the following article (https://www.tandfonline.com/doi/full/10.1080/00220973.2019.1582470):

Fernández-Castilla, B., et al. (2021). Detecting selection bias in meta-analyses with multiple outcomes: A Simulation study. The Journal of Experimental Education, 89(1), 125-144. doi: 10.1080/00220973.2019.1582470

Best,
Mark Assink

Dear Jennifer,

A google search of the archives with:

brings up some relevant discussions; and maybe more with different search terms.

Best,
Wolfgang
