Computes a chi-square test of effect size homogeneity and p-value using effect-size estimates and their standard errors from two or more studies. This test should not be used to justify the use of a constant coeffient (fixed-effect) meta-analysis.
meta.chitest(est, se)
vector of effect-size estimates
vector of effect-size standard errors
Returns a one-row matrix:
Q - chi-square test statitic
df - degrees of freedom
p - p-value
