Kevria replied to Kevria's discussion computing 95%CI of the I^2 statistic; and publication bias in the group Heterogeneity
"Sincerely thanks so much for the informative and concise explanation!! May I further ask few follow-up questions? 4) Should I^2 be computed when k = 2, but both studies are from the same article? e.g. two independent samples reported in the…"

Blair T. Johnson replied to Kevria's discussion computing 95%CI of the I^2 statistic; and publication bias in the group Heterogeneity
"With 1), right I^2 can only be calculated when k>1. With 2), according to Higgins and Thompson's (2002) formulation, I^2 values below zero are rounded up to zero. With the second 2), it looks like a calculation error. With 3), for PET-PEESE,…"

computing 95%CI of the I^2 statistic; and publication bias

Dear all,I am working on a manuscript of my meta-analysis on effectiveness of a program. As indicators of heterogeneity in the effect size estimates, I have obtained the Q statistic and the I^2 statistic from the program Comprehensive Meta-Analysis (CMA) 3.0. Now I am using the formula on page 123 of Borenstein, Hedges, Higgins, & Rothstein (2009) to compute the 95% confidence intervals of the I^2 statistics. But some problems occur.1) When there is only 1 study (k=1), should we (or can we)…See More

minimum number of studies for conducting subgroup analysis

Dear all,I am conducting a meta-analysis on the effectiveness of an intervention on two outcomes (attitudinal and behavioral). The effect size measure is Cohen's d. After computing the Cohen's d, I want to proceed to subgroup analysis and meta-regression. I am looking for resources or answers to the 2 questions I came across below.For instance, one moderator is "interactive approach VS didactic approach", and another one is gender (male VS female). 1) Referring to the Cochrane's Handbook (…See More
