For the following list of data (number of sold cars in every year), apply "exponential smoothing foresting with trend" for the first 4 years only. (i.e find the Forecast including trend) : use: a= 0.1 and B = 0.06 Calculate MAD. Assume the trend is zero and the forecasted value equal real value for the 2012 year. 2012 150 173 166 167 180 185 190 210 199 Equations you may need: 2013 2014 2015 2016 2017 2018 Year 2019 2020 Number of sold cars 4
