I donot think that we will be ever asked to calculate it.Better learn to calculate SFF or standard error of forcast.

now what is SFF or standard error of forecast?

standard error = Standard deviation / n ^.5

Standard error of forecast is a pretty brutual equation, probably good to what the formula looks like but i’ve read several times you can use SEE in its place and get approxmiately the same answer, just a slightly wider interval

SEE = SSE^.5/(n-k-1)

OR

MSE ^.5
