Abstract

hetred reduces the statistical heterogeneity of meta-analysis as measured by I-squared. It uses 2 different algorithms. A sequential one (default) and a combinatorial one (tuples option). Using the combinatorial algorithm can demand extreme CPU resources in case where more than 6-7 studies have to be dropped. Always run the sequential algorithm (default option) to see how many studies have been omitted. The difference between the two is that the combinatorial one might find a better combination omitting fewer studies. Hetred reduces I-squared below a prespecified level. Plugin for Windows users is included. Mac and Linux users please contact author for source file.
