摘要
讨论了不同函数模型对杨赤中估值系数的影响．高斯模型和球状模型会产生负估值系数，指数模型理论上不会导致负估值系数，适当调整负幂指数的参数Ｃ，可降低该模型产生负估值系数的可能性。
This paper discusses the influence of different function models on Yangchizhong estimator coefficient. Gauss model and global model can produce negative estimator coefficient.Theoretically, exponent model cann't produce negative estimator coefficient, adjusting parameter C of negative power exponent model may reduce negative estimator coefficient produced by the model.
