Subject: [R-meta] multiple models in one study
Hi
I want to perform a meta-analysis of the relation between the outcome and
key explanatory variables expressed as regression coefficients.
As a rule, authors report several models with different specifications. I
wonder which regression coefficients should I collect?
In the book Meta-regression analysis in economics and business (Stanley &
Doucouliagos, 2012)
several approaches are described:
- The best-set = ONE estimate from each study, using the KEY regression
from each paper
- The average-set = an average of all coefficients reported in the study
- The all-set = all relevant estimates reported in the study
Which approach is preferable? Are there additional considerations that I
have to take into account?
Regards,
Valeria
