SAS has similar functionality withthe built-in loop of the DATA step. However, the constraints ofDATA step programming greatly limit what tasks a programmer can perform. A programmer cannot, for example, begin a
I have spent days trying to work the logic on some IF, THEN, DO, ELSE statements and every time I get one to work, the other doesn't. I am using SAS 9.2. I have tried consecutive IF, THEN, DO statements to try to make the IF THEN ELSE statements read certain blocks of...
(Another way to look at this is to note that any statement that applies to the whole set of observations involves an implicit loop that steps through all the observations. In Stata, that loop occurs separately for each statement. In SAS, it surrounds the whole sequence of statements.) I al...
The following program uses the "file and put commands" to create and save statements that are needed for the JCL job to run in a file. This part will call the previous defined macro to generate codes for the input databases and SAS part of the JCL program: SUGI 27 Coders' Corner data...
Despite recent guideline statements, there is still wide practice variation in the use of multiple arterial grafts (MAGs) versus single arterial grafts (SAGs) for patients with multivessel disease undergoing coronary artery bypass graft surgery.

Decision rule models (Greco et al.2001) composed of logical statements relating conditions on particular criteria and a decision, e.g., “if\(g_i(a)\succeq r_i\)&\(g_j(a)\succeq r_j\)& ...\(g_k(a)\succeq r_k\), then\(a \rightarrow \)Classtor better” for classificatio...
By using what has been presented in this and part 1 of the series provides what is needed to write statements for most situations. One thing to be cognitive of is that if a query is written poorly the performance will suffer. There are countless post on the Internet about grouping...
In other words, if I wanted to modify the code below to capture all the PTSD diagnosis codes for any of the seven diagnosis code variables (diagnosis_code_1 - diagnosis_code_7), how would you amend the code? I tried to - versus or statements with the other diagnosis code variables but...
