WebJul 30, 2024 · Fitting on the other hand assumes your data is contaminated with error, and you want the polynomial that is the "best approximation" to your data. Here polynomial interpolation does not make much sense since you do not want your function to be reproducing the inherent errors in your data as well. WebOct 2, 2016 · For sure, since there are $9$ data points, a polynomial of degree $8$ will make a perfect fit but any lower degree will do a quite poor job. In any manner, the problem has to be treated using multilinear regression. Using a fourth degree polynomial, the predicted values would be $$\left( \begin{array}{cc} x & y & y_{calc} \\ -2. & +3. & -0.25\\ -8.

WebThe key properties of the polynomial distributions are derived in closed form. 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.
