Re: st: how to generate mean for a secquence of five year of a variable

[Oliver Jones <ojones@wiwi.uni-bielefeld.de>]

Hi,

I have never used -rolling- and just had a quick look at the help
file of it.

Couldn't -rolling- be used for both possibilities, i.e. calculating
the mean for separate blocks of five years and moving blocks, by
specifying the stepsize(5) option?

Best
Oliver
