A piecewise polynomial distribution construction is devised to ensure that it is non-negative over the support interval. A goodness-of-fit measure is proposed to determine the best order of the approximating polynomial.

One again, this method produces the same best fitting line. We can use the same methods with a larger problem. Example 6.4.4: Use the Solver Method on a Larger Data Set. WebMay 20, 2013 · The best fit will be a 9th order polynomial - it will go through each point exactly. However it will be badly behaved because in between the points it will go haywire so the estimates will be worthless. So, like Wayne said, you need to decide on an order.
