Re: p value in fisher

In the online documentation for the Corr procedure, at least for SAS 9.2, there is a detail page on "Fisher's z transformation", search the help for the phrase or go through the documentation on the Corr procedure. There is a section called Details: Corr Procedure that has most of the calculations used.

Re: p value in fisher

i find the equation for calculate P-value when i try to do it by hand it give me different answer from SAS

for example 

r=0.77349 rho=0.6 and n=26 based to the equation the P-value is 0.32381

but the P-value that SAS give me is 0.1204 and you see it is not equal
