Moving average (MA) Calculate the sales using 2, 3, 4, 5, and 6 month moving average values. Forecast and plot the upcoming period’s sales using the moving average series that fits best. Explain why you chose that particular MA. Why is it inadvisable to use the Moving Average approach to forecast far into the future?

how to compute the average speed for each location?
for example the pair is the location. how can I get all the
locations of 1,2,3,4,5,6,7,8,9,10,11,12,13,14 and the speed for
each of them to find the mean.
I tried doing this
df4=df [df [ ['pair', 'speed']]==1].mean() #To get all the pairs
with 1's and it's speeds and getting the mean
df4=df [df [['pair','speed']]==2].mean() #To get all the pairs
with 2's and it's speeds and getting the mean
.

You want to compare how two forecasting methods would perform on
some historical sales data. You will forecast the sales for months
4 through 19, calculate the mean absolute deviation (MAD) for both
methods, and you can claim that the one that has lower MAD
performed better, at least for the historical data.
a) The first method is known as the moving average method. The
forecast for a month will be the average sales of three previous
months. So, forecast...
