Using the same problem$)$ Calculate the MAD for the Weighted Moving Average $2$ periods $($weights of $2$ for most recent and $1$ for time period before..... previously done$)$ and the Exponential Smoothing with alpha $\mathrm{.}3$ and starting forecast of $75...$ previously done$)$ forecasts. What is the MAD for the most accurate forecast?
