Hello Group: Thank you Sigurd and Mark for you insightful suggestions. Below is the solution I used. Best, Tom DATA Std_error_data; SET combined_data; PROC SQL; CREATE TABLE Std_error AS SELECT theta_group ,sample_size, sum_theta_new, SUM((theta_new-sum_theta_new)**2) AS sum_theta_new_diff, SQRT(CALCULATED sum_theta_new_diff/(sample_size-1)) AS Std_error FROM (SELECT theta_group ,theta_new, COUNT(*) AS sample_size, SUM(theta_new)/CALCULATED sample_size AS sum_theta_new FROM Std_error_data GROUP BY theta_group) GROUP BY theta_group; QUIT; ----- Original Message ---- From: Sigurd Hermansen <HERMANS1@WESTAT.com> To: Thomas Schmitt <schmitta1573@yahoo.com>; SAS-L@LISTSERV.UGA.EDU Sent: Friday, January 18, 2008 4:56:42 PM Subject: RE: PROC SQL Thomas: I don't see how the SORT operator/function fits into a SQL SELECT clause. A more serious problem, though, appears in the nesting of SUM functions (whether CALCULATED or not). SAS PROC SQL does not allow that. Try moving the inner SUM to an in-line view or sub=query. S From: owner-sas-l@listserv.uga.edu on behalf of Thomas Schmitt Sent: Fri 1/18/2008 3:07 PM To: SAS-L@LISTSERV.UGA.EDU Subject: PROC SQL Hello Group: Iʼm trying to do a calculation in ROC SQL. The data and code is below. The first column is theta_group and the second column is theta_new. Where I run into a problem is in this line: SUM((theta_new-CALCULATED sum_theta_new)**2). How do I subtract each theta_new from the average sum_theta_new and then sum those values?
