<P>请问，用eviews估计出AR(2)模型的参数后，怎么得到展开的方程表达式？</P>
<P>Dependent Variable: Y
Method: Least Squares

Variable Coefficient Std. Error t-Statistic Prob.

C 7.876779 0.441819 17.82807 0.0000
AR(1) 1.156648 0.110660 10.45226 0.0000
AR(2) -0.208293 0.110161 -1.890803 0.0639</P>
<P>Estimation Command:
=====================
LS Y C AR(1) AR(2)</P>
<P>Estimation Equation:
=====================
Y = C(1) + [AR(1)=C(2),AR(2)=C(3)]</P>
<P>Substituted Coefficients:
=====================
Y= 7.876778541 + [AR(1)=1.156647985,AR(2)=-0.2082934278]</P>
<P>请问怎么把上面的这个 Y= 7.876778541 + [AR(1)=1.156647985,AR(2)=-0.2082934278] 展开？</P>
