The aim of these materials is to help you increase your skills in using regression analysis with SPSS. This web book does not teach regression, per se, but focuses on how to perform regression analyses using SPSS. It is assumed that you have had at least a one quarter/semester course in regression (linear models) or a general statistical methods course that covers simple and multiple regression and have access to a regression textbook that explains the theoretical background of the materials covered in these chapters. These materials also assume you are familiar with using SPSS, for example that you have taken the Introduction to SPSS class or have equivalent knowledge of SPSS. If you are a member of the UCLA community and have questions about these materials, we welcome you to send questions via email to or to visit our consulting services .

Accessing the Data Files
All data files used in the book are available as SPSS version 8 (.sav) files. The are listed below in alphabetical order and can be downloaded by clicking on them.
You can store these data files in any folder on your computer. Our examples will assume that you have stored the files in a folder called c:spssreg , so whenever an example refers to c:spssreg you can change that to the name of the folder where you stored the files on your computer.
It is important to refer to the SPSS manuals to learn about using SPSS. We hope these chapters will introduce you to a number of new SPSS commands, however it is important to have the manuals to show you the detail of the syntax of the commands, examples, and technical explanations of what the commands are doing. Fortunately, if you have SPSS you also should have access to the SPSS manuals from within SPSS by clicking on Help then Syntax Guide. If this is not available, you should reinstall SPSS and choose a custom installation and be sure to check the box that allows you to install the syntax guide.
There may be a number of regression concepts introduced in the chapters that are new to you. Since the chapters focus on how to analyze your data using SPSS (and not the underlying concepts) you may want to have a good regression book to help explain such concepts. Below we list a number of regression books that we would recommend. Each of these books is very good in their own way and yet, each one of them is different. Different individuals prefer different books from the list, and some of them may appeal to your learning style more than others. If you are interested in acquiring one of these books, we would invite you to preview them via our Statistics Books for Loan program. Also note that some of these have corresponding web pages at our SPSS Textbook Examples page.
