In a single-group analysis, there is only one group and one model. Because all model or group specifications are unambiguous, the MODEL and GROUP statements are not necessary. The order of the statements is not important for parsing purposes, although you might still like to order them in a particular way to aid understanding. Notice that the OUTFILES statement is not necessary in single-group analyses, as it is designed for multiple-group situations. Output file options in a single-group analysis can be specified in the PROC TCALIS statement.
