  1. Supplement Fitting Quadratic Models to Data

  2. Best Fit • We have learned from previous sections that the best fitting curve for any given data, is the curve that gives the smallest average error.

  3. Where: • E = Error = Actual Given Value – Predicted Value from the model • SSE = Sum of the Square of the Errors • n = Number of Data Points

  4. Therefore, the average error is:
