Logistic曲线模型和Gompertz曲线模型的修正

Modification of Logistic and Compertz Curve Models

本文提出Ｌｏｇｉｓｔｉｃ及Ｇｏｍｐｅｒｔｚ曲线的修正模型，给出相应的参数估计方法。解释该模型在经济学中的实际意义。修正后的模型可得出高于原曲线模型的预测精度。

Modified Logistic curve model and Gompertz curve model, and the method for estimating corresponding parameters are proposed in this paper.The practical significance of the modified models is explained, which can give higher computational precision than the originals.
