AN OVERVIEW OF APPROACH TOWARDS THE USE OF STATISTICAL MODELS IN META-ANALYSIS
This paper overviews the use of statistical models, fixed as well as random, in meta-analysis. Fifteen proponents and ten opponents have been observed through a qualitative analysis. We found that fixed and random models are unable to explain all the relevant variables, and hence recommend the use of a mixed model.
