Hi,
I would like to compute I² in for my meta-analyses, but I can't find any software to do it. I know that ESCI (the excel file from Geoff Cumming, thanks to him!) can do this math, but the version I've used ( https://thenewstatistics.com/itns/esci/ ) only compute Diamond ratio. I know the old version of ESCI computed I² and Q, but I can't find it (and it is not available on the website).
If someone have an idea, that will help!
Thanks :)
Louis
Hi Louis Violeau ,
Attached you'll find it. However, I recommend:
1. Watching the Dr. Cumming's video explaining how to analyze heterogeneity in terms of fixed/random effects and diamond ratio (this is extended in his book): https://www.youtube.com/watch?v=_bB2k-1Hv9E
2. Running the "metaforest" or "mc.heterogeneity" function within R. Here you have the recent version of the package 'meta' (https://cran.r-project.org/web/packages/meta/meta.pdf) and a very nice hands-on guide (https://bookdown.org/MathiasHarrer/Doing_Meta_Analysis_in_R/).
Hope this help.
Hi Louis
Chapter 6 of this resource contains code and examples for quantifying heterogeneity.

Jamovi (free software) has an add-on module called MAJOR, which does meta-analysis. I don't know whether it has what you are looking for but it is currently in development so you may want to ask the developer to add the feature.
