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. WebFit is typically used for fitting combinations of functions to data, including polynomials and exponentials. It provides one of the simplest ways to get a model from data. The best fit minimizes the sum of squares . The data can have the following forms:
