| This package provides classes to perform curve fitting. |
| |
| <p>Curve fitting is a special case of a least squares problem |
| were the parameters are the coefficients of a function <code>f</code> |
| whose graph <code>y=f(x)</code> should pass through sample points, and |
| were the objective function is the squared sum of residuals |
| <code>f(x<sub>i</sub>)-y<sub>i</sub></code> for observed points |
| (x<sub>i</sub>, y<sub>i</sub>).</p> |
