Recоmpute the fоrecаsts frоm Problem #1 using а one-step аhead 3-month weighted moving average approach and the following weighting system (0.5 for the most recent month, 0.3 for two months prior, and 0.2 for three months prior). Complete the table by finding each month (4-12) forecast and absolute deviation. Then, compute a new Mean Absolute Deviation for the period 4-12 (i.e. MAD4-12). Note: be sure to include your shown work, month by month. Also, make sure to list your forecasted values for periods 4-12 clearly. Your Answer: MAD 4 MA=(64)(.5)+(63)(.3)+(38)(.2)=56.5 MAD = abs (80-56.5)=23.5 5 MA=(63)(.2)+(64)(.3)+80)(.5)=65.8 MAD = abs (48-65.8)=17.8 6MA=(64)(2)+80(3)+48(5)=60.8 MAD = abs(51-60.8)=9.8 7MA=(80+48+51)=55.9 MAD = abs(54-55.9)=1.9 8MA=(48+51+54)=51.9 MAD=abs(39-51.9)=12.9 9MA=(51+54+39)=45.9 MAD=abs(45-45.9)=0.9 10MA=(54+39+45)=45 MAD=abs(63-45)=18 11MA=(39+45+63)=52.8 MAD=abs(59-52.8)=6.2 12MA=(45+63+59)=57.4 MAD=abs(56-57.4)=1.4
