WebNov 14, 2024 · 1. I have produced an OLS regression model where I have trained and tested the data: from sklearn.model_selection import train_test_split X_train, X_test, y_train, y_test = train_test_split (X, Y, test_size = 0.20) I have then created the variable y_preds as follows: X_test = sm.add_constant (X_test) y_preds = results.predict (X_test) I am now ... WebWell, that's where we can use our regression equation that Vera came up with. The predicted, I'll do that in orange, the predicted is going to be equal to 1/3 plus 1/3 times the person's height. Their height is 155. That's the predicted. Y-hat is what our linear regression predicts or our line predicts.
