本文提出用“函数变幅”来比较二次数字模型中因子作用的大小,是一个比较新颖和值得共同探讨的问题。其优点是:在给定条件下,考虑了一次项、二次项和平方项三者的共同作用。文中结论只限于三个因素分别固定在-2、-1、0、1、2相同的水平条件下。但二次数字模型中因子作用的大小,由于固定条件错综复杂,如何考虑以固定二个相同因素,而另一个因素不同,或三个因子都不相同的客观实际,则是一个值得深入研究的问题。所以,对二次数学模型因子作用的大小要作出比较全面的评价,必须结合生产实际做更多的统计工作。
In this paper, it is a relatively new and worth discussing problem to use the “function luffing” to compare the role of factors in the secondary digital model. The advantage is: under the given conditions, the combination of the first term, the second term and the square term are considered. The conclusion of the paper is limited to the fact that the three factors are fixed at the same level of -2, -1, 0, 1 and 2, respectively. However, the size of the factor in the second-order numerical model is an issue that deserves further study because of the complicated conditions, how to consider the objective reality of fixing two identical factors, the other one of them different, or all the three factors being different . Therefore, the size of the role of the secondary mathematical model to make a more comprehensive assessment of the actual production must do more statistical work.
