СКАЧАТЬ to the SAS windowing environment. Otherwise, the exercise can be considered environment-independent. Path references in this book are, however, specific to Microsoft Windows, and may need to be adjusted for other environments such as UNIX, Linux, or z/OS. (SAS University Edition runs in a Linux environment even if you are using a Windows PC.)

      For Instructors Instructors may obtain a complete solutions manual by completing the form found at the “Instructors Solutions” link on the web pages for any of the authors at support.sas.com/publishing/authors, and providing the appropriate credentials. The solutions given for the programming exercises are not the only ones possible. Many of the exercises can be solved in multiple ways. Instructors may choose to share a snippet of output or a graph if they think their students need a little extra help to complete an exercise. The section references that accompany the instructors’ solutions refer to the sections in The Little SAS Book, Sixth Edition where the material is covered. These references are listed only for the corresponding chapter of the exercise even though the answer may use subject matter from a previous chapter.

      We encourage instructors to add their own follow-up questions to any of the exercises for class assignments. In Chapter 9, “Using Basic Statistical Procedures,” we have supplied many extra variables in the data sets so that instructors can append additional questions according to the content covered in their course.

      For the projects in the final chapter, instructors may choose to download and distribute the data for the class to use. Instructors may clean the data for the class as they see fit, or leave the data manipulation to the students instead.
