Regression Analysis for Prediction
Formula
Regression analysis estimates the relationship between variables and enables prediction. The regression equation describes how the dependent variable changes as the independent variable changes.
R-squared (coefficient of determination) indicates how well the model explains the variability of the data. Higher R-squared values suggest a better fit.
Common use cases:
- Sales forecasting from historical data
- Scientific relationship modeling
- Trend extrapolation
