ABSTRACT

To any analyst performing a meta-analysis, the first terminology is proba-

bly fixed-effects versus random-effects models. Therefore to give readers an

introductory and broad view of meta-analysis, we begin by presenting these

models with limited details in this chapter along with the commonly used R

packages of rmeta and meta using two datasets described in Section 3.1. De-

tailed descriptions of these models and their applications will be learned in

future chapters.
