Package org.apache.commons.math3.fitting Description

Classes to perform curve fitting. Curve fitting is a special case of a least-squares problem where the parameters are the coefficients of a function \( f \) whose graph \( y = f(x) \) should pass through sample points, and were the objective function is the squared sum of the residuals \( f(x_i) - y_i \) for observed points \( (x_i, y_i) \).
