Improving the ill-condition of the best square approach polynomial
For the best square approach polynomial, the article analyses the factors which affect the condition-number of normal equations and combined with numerical trial, puts forward the way of centralizing and compressing, which can availably lower its condition-number and improve the ill-condition of the normal equations.
