  1. How it worksHow do the far ends of a data set break the tie between two models that fit the middle?
  2. Worked exampleCompare linear and exponential fits for the data 4, 6, 9, 13.5, 20.25 and pick a winner.
  3. Going furtherWhat happens to each model's prediction ten steps past the end of the data?
