Jun 9, 2013 · To find a residual, the actual y comes from the original data, and the predicted ŷ comes from one of the methods above. Example: Find the residual for x = 102. Solution: From the original data, y = 264. From either of the methods above, ŷ = 267.1. Therefore the residual is y − ŷ = 264−267.1 = −3.1 yards. The smallest value found is the minimum value of the function and the largest is its maximum value.
