| Abstract: | An unbiased factorized chi-square estimator is constructed to deal with the correlated data for linear function fit.The difference between the biased and unbiased chi-square fitting is expounded.In addition,the simplified R-value measurement is quoted to test the conclusion quantitatively. |
