If the outcome variable is nominal (as in the above image), select 2 Outcomes if it has 2 outcomes, or N outcomesif it has more than 2 outcomes. If the outcome variable is ordinal (e.g. low, medium, high), select Ordinal Outcomes.

  3. Drag and drop your outcome variable to Dependent Variable and your predictor to Covariates.

  4. The result is shown in the right panel:
