When does this apply?

For a design in which a categorical outcome with exactly two levels — “recovered” / “not recovered”, say — is modelled on one or more quantitative predictors. The outcome column must be categorical, because the table names the modelled level in words; which level counts as the event is set in the “Modelled event” option. The output is the model’s χ², degrees of freedom and p, and per predictor B, its standard error, the Wald z, p, and the odds ratio with a 95% confidence interval. A categorical predictor is not accepted by this model — you must code it 0/1 yourself.
