The MSE is based on observations from Time 4 to Time 24. Mean Square Error(MSE) \begin{tabular}{|c|c|} \hline Model Specification & 3-Month Weighted Moving Avg \\ \hline Weights & 0.1000 \\ & 0.8000 \\ & 0.1000 \\ \hline alpha & \\ \hline Total & \end{tabular} Use the excel file Final_Exam.xlsx, sheet "Weighted Moving Average" to answer this question. We use 3-month weighted moving average to forecast the DVRs sales in Month 25 as follows. Y^t+1=w1Yt+w2Yt1+w3Yt2 Find the optimal weights which minimize MSE using Excel Solver. Write the minimized MSE below. Round the number to 3 decimal places. (For example, we round 0.12360.124)
