About This Title

MetaWin first published in 1997, allows the user to easily carry out all common meta-analysis calculations on multiple independent studies from a wide variety of disciplines, including medicine, ecology, and the social sciences. One can compare mean effect sizes and confidence limits of different classes of studies with the click of a mouse, and examine the results of within- and between-group heterogeneity using parametric methods as well as resampling tests. MetaWin 2.0 allows users to refine their analyses by choosing which specific groups and individual studies from their data sets they wish to analyze or eliminate. In addition, Version 2.0 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. MetaWin runs on IBM-compatible computers running Windows 95/98/NT/XP, with a minimum 8MB of RAM. Read on for a brief list of new features.

What's New in Version 2.0?

The program comes with its own spreadsheet editor; data can be entered directly into the spreadsheet or read from a text file, a Microsoft Excel file, or a Lotus 1-2-3 file. These files can now be in free matrix format, and data in the editor can be corrected and altered as needed.
Many of the program limitations found in Version 1.0 have been eliminated. There is still a limit on the number of iterations that can be performed for resampling tests (now 64,999), but the number of independent variables, the number of studies, and the number of groups is limited only by the amount of available space on one's hard drive.
The program can now calculate six different effect sizes (Hedges' d, response ratio, odds ratio, rate difference, relative rate, and Fisher's z-transform) from data, rather than two, as in Version 1.0.
The analysis routine is greatly expanded, and now includes additional analyses, such as regression/continuous analysis, cumulative analysis, fail-safe analyses and data exploration techniques.
Graphical analyses such as funnel plots, radial plots, histograms, quantile plots, regression plots, and others are now included (Version 1.0 included no graphics).
A statistical calculator is included so that one may transform test statistics from various studies into a common metric (e.g., correlation coefficients) that may be used to generate effect sizes.

Reviews and Commentary

"Good luck with this important project. We are in an age where the development of software such as this is critical because of the dire need to consolidate information. I have in my possession and have tested a number of meta-analytic software programs and find MetaWin to be the best one currently on the market." George Kelley Director, Meta-Analytic Research Group Northern Illinois University

"MetaWin is a major contribution to ecology. If it catches on like I think it should, the field of ecology may begin to achieve the synthesis everyone seems to want. In fact, the program and documentation is so clear that empirical biologists of all kinds who want to go beyond single studies will love MetaWin." Peter M. Kareiva, University of Washington
