Thoroughly up to date, Cody’s Data Cleaning Techniques The usage of SAS, Third Edition, addresses tasks that nearly every data analyst needs to do – that may be, make certain that data errors are located and corrected. Written in Ron Cody’s signature informal, tutorial style, this book develops and demonstrates data cleaning programs and macros that you’ll be able to use as written or modify so as to make your job of data cleaning easier, faster, and more efficient.

Building on both the creator’s experience gained from teaching a data cleaning course for over 10 years, and advances in SAS, this third edition includes four new chapters, covering topics such as the usage of Perl regular expressions for checking the format of character values (such as zip codes or email addresses) and how to standardize company names and addresses.

With this book, you’ll discover ways to:

  • find and correct errors in character and numeric values
  • develop programming techniques related to dates and missing values
  • deal with highly skewed data
  • develop techniques for correcting your data errors
  • use integrity constraints and audit trails to prevent errors from being added to a clean data set
