Question
You create a regression model with low RMSE and review the best model metrics.
Where on the Residual histogram should the most frequently occurring residual values cluster for your model?
A. 1
B. 0.5
C. 0
D. -1
E. 2
F. -0.5
Answer
C. 0
Explanation
In a regression model with low Root Mean Squared Error (RMSE), the most frequently occurring residual values should ideally cluster around 0 on the Residual histogram. This clustering indicates that the model’s predictions are close to the actual values, minimizing errors.
The Residual histogram presents the frequency of residual values distribution. Residual is the difference between predicted and actual values. It represents the amount of error in the model.
If we have a good model, we should expect that most of the errors are small. They will cluster around 0 on the Residual histogram.
