Need help with Fisher's z test for comparing 2 correlations

chevy37 — Mon, 30 Sep 2013 03:33:16 GMT

Hello,

I have successfully managed to run 2 spearman correlations for 2 independent samples looking at the same variables. I am, however, having trouble using Fisher's z test in order to compare these 2 groups. Below is the syntax and error messages I am receiving.

data five ;

merge WSW keep=Nobs ZVal

----

201

rename=(Nobs=n1 ZVal=z1))

-------

22 22

201 76

ERROR 22-322: Syntax error, expecting one of the following: a name, a quoted string, (, -, :, ;, END, _DATA_, _LAST_,_NULL_.

ERROR 201-322: The option is not recognized and will be ignored.

ERROR 76-322: Syntax error, statement will be ignored.

WSM keep=Nobs ZVal

rename=(Nobs=n2 ZVal=z2));

variance = 1/(n1-3) + 1/(n2-3);

z = (z1 - z2) / sqrt( variance );

pval = probnorm(z);

if (pval > 0.5) then pval = 1 - pval;

pval = 2*pval;

run;

NOTE: The SAS System stopped processing this step because of errors

Please help!

merge WSW(keep=Nobs ZVal rename=(Nobs=n1 ZVal=z1)) WSM(keep=Nobs ZVal rename=(Nobs=n2 ZVal=z2));
