## Package org.apache.commons.math3.fitting Description

Classes to perform curve fitting. Curve fitting is a special case of a least squares problem were 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(xi) - yi for observed points (xi, yi).
