WebDec 30, 2024 · Robust Regression for Machine Learning in Python. Simple linear regression aims to find the best fit line that describes the linear relationship between some input variables (denoted by X) and the target variable (denoted by y). This has some limitations as in real-world problems, there is a high probability that the dataset may have outliers. WebApr 24, 2024 · dummy_regressor.fit(X_train.reshape(-1,1), y_train) Here, we’re fitting the model with X_train and y_train. As you can see, the first argument to fit is X_train and the second argument is y_train. That’s typically what we do when we fit a machine learning model. We commonly fit the model with the “training” data.
