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

This package provides 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 residuals `f(xi)-yi` for observed points (xi, yi).
