We've had some recent requests for a Q statistic to be given for metaanalyses and this is just to let you know that we're onto it and this will be built into the next version.

Just a quick update  the Beta version now includes two tests for heterogeneity  the Q statistic and ISquared  when conducting a metaanalysis. This is now available for download at: http://www.clintools.com/download/ClinTools40Beta.exe (http://www.clintools.com/download/ClinTools40Beta.exe) the statistics are in the advanced printout ("save Metaanalysis To Notepad" button). ;D
Best,

Question here....I was trying to use the test for heterogeneity also and tried to use the link below to get it up and running but there seems to be an error. When I run the test for heterogeneity in the metaanalysis, no values are given. The "test" is there and appears to run but no output. Am I doing something wrong here?? Thanks!

Hi Stacey,
We're getting there  just testing before release. The version you have  does it give a value of "0" (zero)?
Thanks for your patience,
Dev

Thanks for working on this issue!! I copied the heterogeneity section from the example metaanalysis for the version that I have (which I think is the most recent). The output does appear to be "zero" for all of the tests.
HETEROGENEITY
Mean Cohen's d Weighted By Variance: 0
Q Statistic Based On Cohen's d Using Inverse Variance as Weighting: 0, DF: 0
Q Statistic Significance Level (Using Chi Squared Test): Two Tailed p = 0, One Tailed p = 0
I Squared (Higgins & Thompson, 2002) For Cohen's d Calculations Using Inverse Variance as Weighting: 0% of Total Study Variation Due to Heterogeneity.
Thanks again!
Stacey

I hate to bother you but I was wondering how this issue is coming along. I'm getting close to needing to run the metaanalysis for my thesis project. Thanks!
