Shap linear regression
Webb18 mars 2024 · A perfect non-linear relationship. Taking mnth.SEP we can observe that dispersion around 0 is almost 0, while on the other hand, the value 1 is associated mainly with a shap increase around 200, but it also has certain days where it can push the shap value to more than 400.
