Using standard error in meta() and meta3()

Hi Mike and others,

I've been running some three-level meta-analyses using meta3() with standard error as input instead of variance. However, the description of meta() and meta3() only mention the use of variance as input. Although I am aware it is easy to convert standard error to variance I was wondering whether it is ok to use standard error with meta() and meta3().

Thanks for the help all.

Best,
Jasper

Hi Jasper,

No. If you use standard errors to replace the sampling variances, the parameter estimates and their standard errors are wrong except the rare case that the sampling variances (and standard errors) are all one.

If your standard errors are stored as mydf$se, you may easily convert them into sampling variances by
mydf$v <- mydf$se^2

Best,
Mike
