coefficients (beta-values)
Thanks Wolfgang this is helpful much appreciated!
I have another quick question, If I have beta coefficient and standard error from
each study, then is it ok to combine all those values using random effect model?
For example rma(yi, vi), where yi= all beta coefficients from each study and vi=
is the variances for beta coefficients. So the pooled estimate can be explained
as pooled beta and its SE right?
Sorry If my question confused you.
Regards,
Rasheda

Dear Rasheda,
You might want to take a look at this article:
Aloe, A. M., & Thompson, C. G. (2013). The synthesis of partial effect sizes.
Journal of the Society for Social Work and Research, 4(4), 390-405.
https://doi.org/10.5243/jsswr.2013.24
and the help page for escalc() in the metafor package:
https://wviechtb.github.io/metafor/reference/escalc.html#partial-and-semi-
partial-correlations
and this example dataset:
https://wviechtb.github.io/metadat/reference/dat.aloe2013.html
These methods are equally applicable to epidemiological studies.
Best,
Wolfgang

Hi all.
I need help on current development on r-packages, codes, examples and
manuals to conduct Meta analysis of epidemiological studies. Combining
regression coefficients (beta-values).
Thanks in advance.
