Next, we compare your forecasting results from part $($c$)$ F$1$: $33,$ F$2$: $33\mathrm{.}60,$ F$3$: $35\mathrm{.}1...$ you calculated in part c$),$ to the following alternative forecast result for Weeks $13$ for the SCO$3001$ Company: $$ F$1=33,$F$2=33\mathrm{.}4.$F$3=36\mathrm{.}12$

$($i$)$ Which result is a better forecast based on CFE?

Hint: For comparison based on CFE, we need to first calculate the CFE$3($for Weeks $13)$ for

both of the forecasting results, then see which one is closer to $0.$

$($ii$)$ Which result is a better forecast based on regular MAD

Hint: For comparison based on regular MAD, we need to first calculate the rMAD$3($for Weeks $1$

$($iii$)$ Which result is a better forecast based on smoothed MAD $($with $=1,=0\mathrm{.}3)$

$3)$ for both of the forecasting results, then see which one is closer to $0.$

Hint: For comparison based on smoothed MAD, we need to first calculate the smoothed MAD$3($for Weeks $13)$ for both of the forecasting results, then see which one is closer to $0.$

$$ To calculate sMAD$3$ for any one of the forecasts, we have $=||+$

$333$

$(1)2.$ We already know the values of $,3,3,(1),$ so we need to first

figure out the $2$ value for the calculation.

$$ Again based on the formulation, $2=|22|+(1)1.$ We already

know the values of $,2,2,(1),$ so we nee
