WebOct 11, 2024 · Logistic regression predicts the probability of a record belonging to the positive class given features. Since we have two classes, finding the probability of belonging to the negative class is simple: Once we have probability values, it’s easy to convert them to a predicted class. Web1 Answer. You hint at the correct reason in your last paragraph, it is because logistic regression predicts conditional probabilities. I would venture the strong optinion that, regardless of what you learned in class, this. When making predictions, we say that y = 1 if h θ ( x) ≥ .5 and y = 0 otherwise. go kinect business
