*Dear All,*
I am using Seasonal ARIMA model for predicting cloud workloads. I want to
know the running time complexity of building model by the algorithm
implemented in R (I am not sure, is it Yule-Walker?). I want to know if it
It is not Yule-Walker (which is for AR models only).
is polynomial O(n^2) etc. or exponential or linear (O(n)). Can someone
please help.
What is 'n' here? Please read the references for yourself: they will
tell you enough to deduce the answer -- or you could experiment.
PLEASE do read the posting guide http://www.R-project.org/posting-guide.html

PLEASE do.
