Note that “die” is a dichotomous variable because it has only 2 possible outcomes (yes or no). Logistic Regression is found in SPSS under Analyze/Regression/Binary Logistic… This opens the dialogue box to specify the model Here we need to enter the nominal variable Exam (pass = 1, fail = 0) into the dependent variable box and we enter all aptitude tests as the first block of covariates in the model.

Click the Analyze tab, then Regression, then Binary Logistic Regression: In the new window that pops up, drag the binary response variable draft into the box labelled Dependent. Then drag the two predictor variables points and division into the box labelled Block 1 of 1. Leave the Method set to Enter.

Two alternatives would be to use penalized logistic, which is available as the STATS FIRTHLOG extension command or to use DISCRIMINANT, which works even when … Logistic regression does not make many of the key assumptions of linear regression and general linear models that are based on ordinary least squares algorithms – particularly regarding linearity, normality, homoscedasticity, and measurement level..

In that case, relative risk of each category compared to the reference category can be considered, conditional on other fixed covariates.
