st: Correlation coefficients and the CORTESTi program - again
Dear statalist members;
I did not get any replies to my query, so I let me ask
it a different way:
The program -cortesti- compares the correlation
coefficients by constructing a Z-score of the
difference as follows:
where corr1 and corr2 are the 2 correlation
coefficients and n1 and n2 the corresponding sample
sizes. Z is the test statistic use to compute a
p-value. Does anyone know of a different approach?
Thank you in advance
