WebAug 24, 2024 · Curve fitting is a numerical process often used in data analysis. Its essence is to apply a certain model (or called a function or a set of functions) to fit a series of discrete data into a smooth curve or surface, and numerically solve the corresponding parameters, thereby obtaining the relationship between the coordinates represented by the discrete … WebAbout Polynomial Models. Polynomial models for curves are given by. y = ∑ i = 1 n + 1 p i x n + 1 − i. where n + 1 is the order of the polynomial, n is the degree of the polynomial, and 1 ≤ n ≤ 9. The order gives the number of coefficients to be fit, and the degree gives the highest power of the predictor variable. WebMar 27, 2015 · Therefore, using your x and y values, this is what I get: A = 1.3882 b = -11.508.
