Dear Metafor members,
I was wondering if anyone could help unravel the reasoning behind carrying out a principle component analysis compared to a multivariate meta-analysis between outcomes.
For instance, a literature review collected data on enzyme kinetics from a range of published papers. They then analysed the relationships between the kinetic parameters using PCA. Surely, would a multivariate meta-analysis not be better since it will be taking into account any between study-heterogenity which would have otherwise been overlooked if a normal PCA was carried out?
Hope you understand what I mean.
