The LIFETEST Procedure

ODS Table Names

PROC LIFETEST assigns a name to each table it creates. You can use these names to reference the table when using the Output Delivery System (ODS) to select tables and create output data sets. These names are listed in Table 56.6. For more information about ODS, see Chapter 20: Using the Output Delivery System.
