双对数模型对模型模拟误差的放缩问题探讨
The Discussing of the Problem of Enlarging or Reducing Simulation Error by Double Logarithmic Model
【摘要】 对双对数模型lg Y=a0+a1lg X1+a2lg X2+…+anlg Xn与其对应的指数模型y=c0xa11xa22…xann的模拟相对误差的关系进行了探讨,指出双对数模型具有放大和缩小指数模型相对误差的特性.对二者的关系进行了理论推导和实例验证,并给出了二者的定量关系式.
【Abstract】 The relation between the simulation error of double logarithmic model and that of the corresponding exponent model is discussed here.We found that logarithmic model have the characteristic of enlarging or reducing the simulation error of exponent model.The phenomena is explained from theory analysis and model result.The quantify formula of the relation between simulation error of double logarithmic model and that of the corresponding exponent model is founded in this paper.
