Thanks I will try this, does the same trick applies to correlation also since I would also want to calculate correlation and present results in table form

Hi, I guess I have confused you!

let's try this, you said you have data for 1997, 12 months for 1997,
i.e, the time axis shows you 12 points ( l 1:12)

for MAM

yes? let p = (obsrved-model)
yes? let q = p^2
yes? let r = q[l=3:5@sum] !for MAM
yes? let s = r/3
yes? let m = s^0.5
yes? plot m

For OND

yes? let p = (obsrved-model)
yes? let q = p^2
yes? let r = q[l=10:12@sum] !for OND
yes? let s = r/3
yes? let m = s^0.5
yes? plot m
