Least Squares Approximation

 Description Calculate a least squares approximation using specified data points.

Least Squares Fit of Data by a Specified Curve

List of Data Points:

 > $\left[\left[{2}{,}{-}{1}\right]{,}\left[{4}{,}{3}\right]{,}\left[{6}{,}{-}{7}\right]{,}\left[{7}{,}{5}\right]{,}\left[{9}{,}{-}{2}\right]\right]$
 $\left[\left[{2}{,}{-}{1}\right]{,}\left[{4}{,}{3}\right]{,}\left[{6}{,}{-}{7}\right]{,}\left[{7}{,}{5}\right]{,}\left[{9}{,}{-}{2}\right]\right]$ (1)

Fitting Curve:
