Nettet16. mar. 2024 · 1 Answer. Sorted by: 1. In order to learn the model in a supervised manner (Logistic regression is the model that need to be learned), you need to tell a model what is the class variable in your data. For Logistic regression which is a classification model, the class variable must be discrete (it represent few classes in data).
