用eviews 做出数据，大家帮忙把公式写出来一下，谢谢！！
表达成y= c+c1y（t-1）。。。。的形式，谢谢！！

DY

Estimation Command:
=====================
LS DY C MA(2) MA(3) MA(7)
Estimation Equation:
=====================
DY = C(1) + [MA(2)=C(2),MA(3)=C(3),MA(7)=C(4),BACKCAST=2]
Substituted Coefficients:
=====================
DY = -9.170562995 + [MA(2)=-0.2382187951,MA(3)=0.2636569059,MA(7)=0.4400821495,BACKCAST=2]
