Question of the day

As more variables are added to a linear model, the training MSE generally does what?

Explanation:
When you fit a linear model with least squares, you’re choosing the best linear combination of the predictors to minimize the sum of squared residuals on the training data. Adding more predictors expands the space of possible fits. The key point is that you can always fall back to the old fit by setting the new predictor’s coefficient to zero, so the new, larger model can’t be worse than the old one in terms of training error. Therefore the residual sum of squares cannot increase with more variables; it can stay the same or decrease. Since training mean squared error is the residual sum of squares divided by the number of observations, it likewise cannot increase and typically decreases when you add informative variables. This reflects the intuition that more predictors give the model more flexibility to capture patterns in the training data, though it can raise overfitting risk for unseen data.
