依据分析指数函数回归模型建立的预选条件的过程,获得了在预选条件满足时指数函数回归模型参数的预选条件法估计公式,通过实例应用预选条件法建立指数函数回归模型,并与最小二乘法建立的指数函数回归模型进行比较:预选条件法建立模型的残差平方和比最小二乘法小,模型更可靠。
依據分析指數函數迴歸模型建立的預選條件的過程,穫得瞭在預選條件滿足時指數函數迴歸模型參數的預選條件法估計公式,通過實例應用預選條件法建立指數函數迴歸模型,併與最小二乘法建立的指數函數迴歸模型進行比較:預選條件法建立模型的殘差平方和比最小二乘法小,模型更可靠。

In the course of analysis of preselected conditions based on exponential function regression model, precondition estima?tion formula is obtained when pre -conditions are met with law exponential regression model parameters. Exponential regression model is established by applying preconditions method and the establishment of an exponential function with the least squares method to compare the regression model:the sum of squared residuals of models established on preconditions is smaller than least squares method, and model is more reliable.
