1. SAS ® Regression Essentials

2. 2 List the components of a SAS program. Open an existing SAS program and run it. Objectives

3. 3 DATA steps are typically used to create SAS data sets. PROC steps are typically used to process SAS data sets (that is, generate reports and graphs, edit data, and sort data). A SAS program is a sequence of steps that the user submits for execution. Raw Data DATA Step Report SAS Data Set PROC Step SAS Programs

6. 6 Open the SAS program “example.sas.” Submit the program and examine the results. Data for today's class located at http://www.missouri.edu/~baconr/sas/reg Exercises

7. 7 Learn the two fundamental SAS syntax programming rules. Learn to create a SAS dataset from text data. Locate the data for this course Write a Data Step to read a course data file. Objectives

8. 8 SAS statements have these characteristics: usually begin with an identifying keyword always end with a semicolon data staff; input LastName $ FirstName $ JobTitle $ Salary; datalines; …insert text here… run; proc print data=staff; run; Fundamental SAS Syntax Rules
