The MSE is based on observations from Time 4 to Time 24. Mean Square Error(MSE) \begin{tabular}{|c|r|} \hline Model Specification & 3-Month Weighted Moving Avg \\ \hline Weights & 0.1000 \\ & 0.1000 \\ & 0.1000 \\ \hline alpha & \\ \hline Total & \\ \hline \end{tabular} Use the excel file Quiz4.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. (Fill in a number, without any punctuations or spaces. Round the number to 4 decimal places.)
