Hello,
I am trying to evaluate the correlation between two independent populations via PROC CORR and Fisher's z test. Is it possible to evaluate these two correlations with proc corr (or some other procedure) without inputting an entire dataset and using just the coefficients and sample sizes?
Thank you.
If you have a variable that represents the count of the number times a record should be repeated for your analysis variable appears then use that in a Freq statement;
Proc corr data=yourdata;
var analysisvar;
Freq CountVariableName;
run;
A data step solution would look like:
data have;
input r n;
datalines;
0.1 20
0.4 33
-0.15 108
;
data want;
set have;
fishz=artanh(r)*sqrt(n-3);
prob=0.5*(1-cdf('NORMAL', abs(fishz)): /* Two tailed test */
run;
