I have also tried the following code: sets i index of the forecasting period /1,2,3,4/ ; Alias (j,i) ; scalar ii week to predict /4/ parameters Y(i) historical value / 1 2 2 4 3 6 4 8 / ; variables F(i) forecasted value b(j) coefficent e(i) error etotal total error ; equations eq1(i), eq2(i), eq3; e...

What is wrong with my code below? I get these errors: Error 187: Assigned set used as domain b(j) coefficent Error 148: Dimension different eq1(i).. F(i) =e= sum(j,b(j)*Y(i-j)) ; Error 147: Real value for lag operator expected eq1(i).. F(i) =e= sum(j,b(j)*Y(i-j)) ; Here is the full code: sets t tota...
