MetaWin 2.1

MetaWin allows the user to easily carry out all common meta-analysis calculations on independent studies from a wide variety of disciplines, including medicine, ecology, and the social sciences, compare mean effect sizes and confidence limits of different classes of studies, and examine the results of within- and between-group heterogeneity using parametric methods as well as resampling tests. The program allows users to refine their analyses by choosing which specific groups and individual studies from their data sets they wish to analyze or eliminate. Also, it allows users to calculate any of six different effect sizes from their data, and can be used for a variety of statistical meta-analytic models.
