Dear All,
I want to make forecast but I'm not sure how to make average I want....
It is difficult to explain with words so I made picture and excel sample file.
1, I set average point. Forecast will begin from this month.
2, Count month from final actual month to average point. in this case, "4 month"
3, [Average point before 4 month and after 4 month] is scope of average
4, Extend forecast with reduction rate
5, I make final result data set
It is very greateful if you could help me....
