WebJan 18, 2024 · First of all, let's remember that model interpretation is always contextual (depends on your data and what are you trying to achieve). However, I'll try to explain some general points. You're in a tricky scenario. The low R squared means that your model only explains 7% of the dependent's variation. WebDec 2, 2024 · In the case of a factor with 2 levels, e.g. "red" and "blue", it's obvious that using the k − 1 1hot method is equivalent to choosing the k 1-hot method. This is because NOT blue implies red. In this case, there is no difference. But for k > 2 categories, you'll need k − 1 binary splits to isolate the the omitted level (the k th level).
