Hello,
I am having some problems with fitting an ARMA model to my time series data
(randomly generated numbers). The thing is I have tried many packages
[tseries, fseries, FitARMA etc.] and all of them giving very different
results. I would appreciate if someone could post here what the best
thank you very much for your suggestion!
I tried to do that with the psf I need to use: the 3 parameters Lognormal. I

statistical analysis]

a) read the posting guide

c) read ?optimize and learn to specify the interval

Strings are not glamorous, high-profile components of R, but they do
play a big role in many data cleaning and preparations tasks. R
provides a solid set of string operations, but because they have grown
organically over time, they can be inconsistent and a little hard to
learn.

That concern has nothing to do with centering variables before including them

Your multiple significance testing strategy is not based on statistical
