Logistic Regression Using SAS®: Theory and Application

1.4. Computing

All the computer input and output displayed in this book was produced by and for Release 6.12 of the SAS System. Occasionally, I point out differences between the syntax of 6.12 and earlier releases. I use the following convention for presenting SAS programs: All SAS keywords are in uppercase. All user-specified variable names and data set names are in lowercase. In the main text, both SAS keywords and user-specified variables are in uppercase. In the output displays, nonessential output lines are often edited out to conserve space.
