The PHREG Procedure

ODS Table Names

PROC PHREG 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 separately in Table 85.15 for the maximum likelihood analysis and in Table 85.16 for the Bayesian analysis. For more information about ODS, see Chapter 20: Using the Output Delivery System.

Each of the EFFECT, ESTIMATE, LSMEANS, LSMESTIMATE, and SLICE statements creates ODS tables, which are not listed in Table 85.15 and Table 85.16. For information about these tables, see the corresponding sections of Chapter 19: Shared Concepts and Topics.
