Feb 26, 2014 at 18:39 | comment | added | kosa | @Glen_b: I think I am getting clarity on what is going on here, but stuck at point on how s(t) is 10.3 for first row in this case? Based on formula, I think L(t-1), b(t-1) and s(t-m) are zero for this row right? Which should bring s(t) to ZERO. Any input here? | |
Feb 26, 2014 at 4:53 | comment | added | Glen_b | I'd use the error-correction formula, and the starting values from table 7.9. The $s$ term is easier to understand if you follow through the example. | |

Feb 26, 2014 at 4:44 | comment | added | Glen_b | $\hat{y}_{t+h|t}$ means "the forecast at time $t+h$, given data up to time $t$". So no, it's not the next-period forecast (unless $h=1$), it's the forecast for $h$ periods ahead from time $t$, using information available at time $t$. | |
