Logistic Regression

How to perform a logistic regression in jamovi:
  1. You need one categorical nominal ordinal dependent variable (nominal or ordinal), and at least one continuous explanatory variable.
    A correct setup should look similar to this:


  2. Logistic regression can be found by selecting AnalysesRegression. If the outcome variable is nominal (as in the above image), select 2 Outcomes if it has 2 steps / different values, or N outcomes if it has more than 2 steps. If the outcome variable is ordinal (e.g. low, medium, high), select Ordinal Outcomes.


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


  4. The result is shown in the right panel:


  5. A little more comprehensive introduction into this statistical method is provided by this two videos, explaining logistic regression with two levels (to predict eg gender or clinical vs. control group ) and with more than two levels (to predict, e.g., food preferences: fast food, healthy food, high protein food, vegan food, etc.).
