The evaluation criteria of optimal curve fitting

WEI Yu-ye,ZHAO Feng-yang(Department of Architecture and Decoration Engineering,Jiangxi Vocational Technical Institute of Industrial Engineering,Jiangxi Pingxiang 337055,China)  
This paper discussed the evaluation criteria of curve fitting model selection.The fitting quality can be evaluated from two aspects.On the one hand,making the error of fitting the data is as small as possible.On the other hand,ensuring that linear shape of the curve is best.Some new evaluation criteria were proposed.Experiments proved the feasibility of these evaluation criteria.
