MY META-ANALYSIS PROGRAMS
I have written 3 programs that implement the procedures described by Fleiss (1993). They are available for download in zip-file format (because Angelfire/Lycos blocks download of .exe files). You will need a zip-file utility (such as WinZip) to open them. If you don't already have such a utility, you can no doubt find several free ones at sites such as www.download.com. I use PowerArchiver.
- MACONTW.zip is for continuous (or interval scale) variables, and requires one to enter (or read from a comma-separated text file) a study number, N, Mean, and SD for both the Treatment and Control groups for each trial or study.
- MA2X2W.zip is essentially the same, but is for use with binary outcomes. Instead of entering means and standard deviations, however, you can simply enter the 4 cell counts.
- MAGENERAL.zip is a general purpose program that requires you to enter a study number, total N, some measure of effect size (e.g., the natural log of the odds ratio) and its variance for each study. It requires a bit more data preparation than the others, but can be used for any measure of effect size. An SPSS syntax file version version is also available.
All 3 programs allow you to write the results to a text file. The programs were written using Runtime Revolution, which does not have the density functions I would need to compute p-values, so these are not given. However, they can be obtained easily using resources such as:
Here is a suggestion about how to cite my programs, should anyone have the need.
