RE: Analyses: I ran bivariate correlations, what are my 2nd level beta values?
They represent Fisher-transformed correlation coefficient values, i.e. atanh(r), where r is the correlation coefficient between the source area and target area (voxels or regions)"

If the 2nd level beta values for correlation are Fisher-transformed correlation coefficient values (rZ) -- then what do the 2nd level beta values represent? R-squared or unstandardized beta? How are people reporting these in papers?
Cheers,
