Deliverable:
– A phrase doc answering the next questions
Utilizing the Climate.csv dataset from Module four
Half 1: Metrics for Analysis
1. Calculate the next metrics: imply absolute error, imply squared error, root imply
squared error, and the R2 rating. Use the next code samples:
print(‘Imply Absolute Error:’, metrics.mean_absolute_error(y_test,
y_pred))
print(‘Imply Squared Error:’, metrics.mean_squared_error(y_test,
y_pred))
print(‘Root Imply Squared Error:’,
np.sqrt(metrics.mean_squared_error(y_test, y_pred)))
print(‘R-squared Rating:’, regressor.rating(X, y))
Half 2: Mannequin Refinement
1. Rerun the linear regression mannequin from Module four, however change the share of information
which can be used for testing. Strive utilizing zero.25 and zero.three.
2. Calculate the identical metrics from above.
three. Use a scatter plot to visualise all three fashions.
four. Consider the three fashions. Are any of them underfit or overfit? Which % of testing knowledge
carried out finest?
