How to Calculate Residuals in Regression Analysis
- https://www.statology.org/how-to-calculate-residuals-in-regression-analysis/
- Notice that the data points in our scatterplot don’t always fall exactly on the line of best fit: This difference between the data point and the line is called the residual. For each data point, we can calculate that point’s residual by taking the difference between it’s actual value and the predicted value from the line of best fit. See more
