looking for a written out answer rather than an excel step by step. thank you!

Question 1) (35 points) Quarterly demand values for flowers at a wholesaler are as shown below. Forecast quarterly demand for year 5 using simple exponential smoothing with =0.35 as well as Holt's model with =0.35 and =0.25. Which of the two methods do you prefer? Why? (Hint: You need to calculate forecasting accuracy measures to choose the best model). Table 1 - Quarterly Demand (in Thousand dollars) Forecast demand using the simple exponential smoo =0.1,Lt+1=Dt+1+(1)Lt,Ft+1=Lt Trend-Corrected Exponential Smoothing (Holt's Model) Obtain an initial estimate of level and trend by running a linear regression Dt=at+bT0=a,L0=b In Period t, the forecast for future periods is Ft+1=Lt+Tt and Ft+n=Lt+nTt Revised estimates after observing demand for Period t Lt+1=Dt+1+(1)(Lt+Tt)Tt+1=(Lt+1Lt)+(1)Tt
