Missing Data in Meta-Analysis

  • Chapter
Meta-Analysis with R

Part of the book series: Use R! ((USE R))

Abstract

In this chapter we discuss issues raised by missing data. In Sect. 6.1 we discuss how to explore the robustness of our inference to different assumptions about missing outcome measures, while in Sect. 6.2 we describe an imputation approach which may be used when a study does not report the precision.
