说明: 实验二 可化为线性的非线性回归模拟
计量经济学实验
一 实验目的:
(1) 掌握可化为线性的非线性回归模型的估计方法。
(2) 掌握参数的线性约束检验方法。
二 实验要求:应用教材第91页第11题做回归分析并判断。
三 实验原理:普通最小二乘法、模型参数受约束检验法。
四 预备知识:最小二乘法估计原理、t检验、F检验。
五 实验步骤
1 建立工作文件并录入数据
建立Workfile后,进行数据录入工作,方法:在主界面命令栏键入data Y K L,得到表格,然后输入相应的数据,结果如图1.1所示。
(Experiment 2 can be turned into a linear nonlinear regression simulation experiment: (1) linear control can be turned into non-linear regression model estimation. (2) Linear constraint control testing methods. Second test requirements: Application materials Page 11 of 91 questions to do regression analysis and judgments. Three experimental principle: ordinary least squares method, the model parameters to be bound test. 4 Prerequisites: Principles of least squares estimates, t test, F test. Five steps to an experiment to establish the working paper and data entry after the establishment of Workfile, data entry work method: the main interface command bar type data YKL, get the form, and then enter the appropriate data, the results shown in Figure 1.1.)
