➤ Why should I add regression or smoothing to a price plot?
Regression or smoothing clarifies the underlying price trend amid noisy measurements. A linear or multivariate regression gives an equation you can use for prediction and interpretation. Use polynomial fits or kernel smoothing for nonlinear patterns. Always check residuals and R-squared to assess fit and avoid overfitting when choosing model complexity.
