## 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 $$(x_i, y_i)$$.
