@mean for selected time periods

Postby vytama » Fri Dec 01, 2017 12:39 pm

Hello,
I have a monthly time series and I would like to take an average of t, t-12 and t-24. is there a way to select an average of the three observations?

something like that:
series a = @mean(value at t, value at t-12, value at t-24)?
Thank you

Code: Select all

series a = (x+x(-12)+x(-24))/3
