The MIXED Procedure

ODS Table Names

Each table created by PROC MIXED has a name associated with it, and you must use this name to reference the table when using ODS statements. These names are listed in Table 58.22.

In Table 58.22, "Coef" refers to multiple tables produced by the E, E1, E2, or E3 option in the MODEL statement and the E option in the CONTRAST, ESTIMATE, and LSMEANS statements. You can create one large data set of these tables with a statement similar to the following:

ods output Coef=c;

To create separate data sets, use the following statement:

ods output Coef(match_all)=c;

Here the resulting data sets are named C, C1, C2, etc. The same principles apply to data sets created from the "R," "CholR," "InvCholR," "RCorr," "InvR," "V," "CholV," "InvCholV," "VCorr," and "InvV" tables.

In Table 58.22, the following changes have occurred from SAS 6. The "Predicted," "PredMeans," and "Sample" tables from SAS 6 no longer exist and have been replaced by output data sets; see descriptions of the MODEL statement options OUTP= and OUTPM= and the PRIOR statement option OUT= for more details. The "ML" and "REML" tables from SAS 6 have been replaced by the "IterHistory" table. The "Tests," "HLM," and "HLPS" tables from SAS 6 have been renamed "Tests3," "HLM3," and "HLPS3," respectively.

Table 58.23 lists the variable names associated with the data sets created when you use the ODS OUTPUT option in conjunction with the preceding tables. In Table 58.23, $\text{[math]}$ is used to denote a generic number that depends on the particular data set and model you select, and it can assume a different value each time it is used (even within the same table). The phrase model specific appears in rows of the affected tables to indicate that columns in these tables depend on the variables you specify in the model.

Caution: There is a danger of name collisions with the variables in the model specific tables in Table 58.23 and variables in your input data set. You should avoid using input variables with the same names as the variables in these tables.
