Use this text box to specify variables to use as additional effects beside the corresponding data values from the tall Input SAS Data Set in the model.
The (Cox) model fitting will be adjusted for these covariates.
To Specify One or More Covariates:
8
Type one or more effects in the text field.
8
If you specify more than one effect, then you must separate the effects with spaces.
8
To specify interactions between effect, type an asterisk (*) between the effects. For example, assuming A and B are listed as class variables, typing A B A*B specifies variables A and B, and the interaction between A and B as effects.
8
A vertical bar (|) can be used to create main effectsand interactions. For example, typing A|B is the same as typing A B A*B.
