我建立了一简易宏观经济联立方程模型预测GDP,用两阶段最小二乘法能估计出各变量系数,但建立model后不能求解,系统提示如下:
Repetitions 1-1: 1 failure(s) 22:22:06
Solve terminated - Unable to compute due to missing data in "CHU = @COEF(8) * CHU(-1) + @COEF(9) * CHU(-2) + @COEF(10) * TENGDP ...
Simulation terminated before specified successful repetitions
0 successful repetitions, 1 failure(s)
请问是什么原因?非常感谢啦!本人对联立方程模型较陌生,目前在做一些宏观经济课题,有兴趣的可以一起探讨哦!
