ABSTRACT
So far we have illustrated all the concepts in the output from meta-analysis
using R except heterogeneity measures. Discerning readers may have noticed
that whenever we called metabin or metacont from R package meta for meta-
analysis as seen in Chapters 4 and 5, two other items appeared in the output
as Quantifying heterogeneity and Test of heterogeneity. These hetero-
geneity measures are discussed in this chapter.
