Multiple Choice

Which of the following statements a) , b) or c) is false?

• A) Among the many metrics for regression estimators is the model's coefficient of determination, which is also called the R² score.
• B) To calculate an estimator's R² score, use the sklearn.metrics module's r2_score function with the arrays representing the expected and predicted results, as in: In [44]: from sklearn import metrics
• In [45]: metrics.r2_score(expected, predicted)
• Out[45]: 0.6008983115964333
• C) R² scores range from 0.0 to 1.0 with 1.0 being the best. An R² score of 1.0 indicates that the estimator perfectly predicts the independent variable's value, given the dependent variable(s) value(s). An R² score of 0.0 indicates the model cannot make predictions with any accuracy, based on the independent variables' values.
• D) All of the above statements are true.
