The SAS Viya analytical actions offer great flexibility and generality for specifying covariate effects. But the generality does not get in the way if you have a simple model. Each model parameter in a SAS Viya analytical action requires at least two subparameters:
The argument for depVar is just the name of the dependent variable. Similarly, for some simple linear models, the argument for effects is just a list of the names of all the predictors. However, additional subparameters of effects enable you to specify more complex and versatile models, as shown in the following sections.
