Subject: Dear R experts, I have a question about meta-analysis
Dear R experts,
Greetings from China! I'm Zhang in the College of Education, Zhejiang University, and I am recently running a meta-analysis. Since research using the randomized controlled trial (RCT) often dismissed reporting the correlation (r) between multivariate outcomes, for instance, a study measuring students' gains on problem solving skills with three aspects and reported the pre-post scores respectively, but obviously these three aspects were correlated. I wonder if and how I could integrate the effect sizes among these three aspects into an overall effect size without getting the concrete 'r'? Could R project and (or) function help me solve this problem?
Best,
Zhang
