Paper Abstract

In the accuracy estimation of the classical least square method, the effect of systematic error has been neglected, so that it can't fully reveal the credibility of least square estimation. In this paper the authers analyse the feature of systematic component of uncertainty of the least square estimation and propose a methad to analyse and synthesize the systematic and random components, so that a complete statement of uncertainty of the least square esitmation is obtained.
