Description of the Raw Data File PATIENTS.TXT
The raw data file PATIENTS.TXT contains both character and numeric variables from a typical clinical trial. A number of data errors were included in the file so that you can test the data cleaning programs that are developed in this text. The programs in this book assume that the file PATIENTS.TXT is located in a directory (folder) called C:\CLEANING. This is the directory that is used throughout this text as the location for data files, SAS data sets, SAS programs, and SAS macros. You can modify the INFILE and LIBNAME statements to fit your own operating environment.
