Re: [R] Mean effect size in meta-analysis using Metafor

Dear Carlijn I wonder whether http://www.metafor-project.org/doku.php/tips:comp_two_independent_estimates answers your question? If you had given us an example of your fitting procedure we might know for sure. On 12/12/2015 15:35, Carlijn . wrote: Hi all, I have a question about

Re: [R] R: forest plot metafor

No, this is not possible. But you can just add the weights yourself. One difficulty here is that you want the weights to the right of the estimates and corresponding CIs and those are always placed at the right of the figure. One possibility would be to make the right margin large and then use

[R] Mean effect size in meta-analysis using Metafor

Hi all, I have a question about doing a meta-analysis, in particular a three-level meta-analysis using Metafor. I have estimated the mean overall effect size of males by using two different ways: 1. moderator analysis (male = 0, female = 1) using the whole data set 2. intercept-only

[R] R: forest plot metafor

Many thanks to Professor Michael Dewey for his time. I apologize for the error about the claim to obtain weights from escalc and I realise that the weights are a function of the fit, not the data. weights(res) is OK to extract the weights from the fitted object and to put them in the data

Re: [R] Mean effect size in meta-analysis using Metafor

**If** I understand correctly, this is because of correlation in effects due to non-independence between males and females in the data. As this is primarily a statistical, not an R programming, issue, I suggest you post on a statistics list like stats.stackexchange.com. Better yet, talk with a
