What is Polynomial Least Squares Fitting Guide about?

This document summarizes the process of performing a least squares fit to polynomial data. It begins by reviewing a linear least squares fit, then extends this to quadratic and higher order polynomial fits. For a quadratic fit, the chi-square is minimized to obtain three equations in three unknowns (the coefficients a, b, and c). These coefficients can be solved for using determinants of 3x3 matrices. The process generalizes straightforwardly to higher order polynomials by using higher dimensional determina
