WebOct 25, 2016 · The normal equations will solve the general case. In your specific case, the values of b ( t) are symmetric around t = 1, so the parabola must be A ( t − 1) 2 + ( C − 1). Using the point at t = 1 we can see that C = 2, then a quick check shows A = 1 and we have b ( t) = ( t − 1) 2 + 1, which fits the points perfectly.

The quality of … 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.

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.
