.- help for ^corcor^ (STB-32: sg52) .- Testing dependent correlation coefficients ------------------------------------------ ^corcor^ ^var1^ ^var2^ ^var3^ [^if^ expr] [^in^ range] ^corcori^ ^corr1^ ^corr2^ ^corr3^ ^n^ Description ----------- This is a test of whether two correlations, having one common variable, are equal. That is, a test of whether corr(x1x2) = corr (x1x3). The common variable (x1) must be entered first; the other two may be entered in any order. The immediate version asks for the correlation of x1x2 first, then x1x3, then x2x3, and finally the sample size. The non-immediate version calls fisher.ado (the immediate version calls "fisheri.ado"); these ado files use the fisher z transformation for the correlations coefficients--see @fisher@.
