In fact, I need it in the general case, not only for an ARMA process.
Unfortunately, I have no reference to give so I will code it. Sorry for
the trouble.

Hello!
I am looking for a function which computes the maximum likelihood
estimator of the autocorrelation function for a gaussian time series.
Does a such function already exist in R?
The estimator by default in R, acf(), uses the method of moments.
Thanks a lot,
Alain
