Webb1 Answer. The linear regression module indeed does not have a predict_proba attribute (check the docs) for a very simple reason: probability estimations are only for classification models, and not for regression (i.e. numeric prediction) ones, such as linear regression.

Webb8 aug. 2024 · 3 Answers. It is asking for 2 features per sample. But you are passing the 11. Do it like this. Of course, this means your model will only use the first two features. You have to make combination of the code you wrote. You can only plot 3 axis at a time. x,y is what you give and z is the contour plane.
