Find error and freshen up facts simply utilizing SAS!
Thoroughly up-to-date, Cody's facts cleansing ideas utilizing SAS, 3rd Edition, addresses projects that just about each information analyst must do - that's, ensure that info blunders can be found and corrected. Written in Ron Cody's signature casual, educational sort, this booklet develops and demonstrates info cleansing courses and macros for you to use as written or alter with the intention to make your activity of knowledge cleansing more uncomplicated, quicker, and extra efficient.
Building on either the author’s event won from educating a knowledge cleansing direction for over 10 years, and advances in SAS, this 3rd variation comprises 4 new chapters, protecting issues resembling using Perl general expressions for checking the structure of personality values (such as zip codes or e-mail addresses) and the way to standardize corporation names and addresses.
With this publication, you are going to learn the way to:
- find and proper mistakes in personality and numeric values
- develop programming thoughts concerning dates and lacking values
- deal with hugely skewed information
- develop thoughts for correcting your facts error
- use integrity constraints and audit trails to avoid error from being extra to a fresh info set
