摘要
根据Logistic曲线和Gompertz曲线的共性和个性,以对数误差平方和最小为目标,建立了组合预测模型,并以实例说明了该模型的优越性.
According to the general character and individual character of both Logistic curve and Gompertz curve, and at the target of the least square sum of the logarithmic error, we establish a kind of combinatorial prediction model and analyse its superiority by a practical example.
