Hello everyone,

I am conducting a meta analysis for the first time and for some papers  
I need to calculate the wanted effect sizes (Cohen's d) of main  
effects and interactions of 2x2 repeated measures ANOVAs.  
Unfortunately, I have found barely information about how to do this so  
far (actually only for one-way ANOVA).

Is it possible to do this only with F-values, degrees of freedom or  
directly from (partial) eta squared (as often reported)? Thus,  
assuming we have no information of means, MSE, etc.

Thank you very much in advance!

Best regards,
