Hello, I was registered in the gretl users list but now I want to contribute with some code I have been working in.

The problem is that the code is in java and is rather long (10 classes) but the package would be unique since I do not know any other softare that estimates SARFIMA models in only one step using pseudo M. Likelihood estimation (other packages uses the 2 step approximation-first estimating d using a consistent semi-parametric estimation and then the phi's and theta's).

I am not the developer of the code, a friend of mine (engineer) made it following my directions so i do not know how to re-write it in C.

So... is it possible for you to re-write the entire package in C?

I think it is a great opportunity to expand gretl capabilities and therefore the ammount of potential users.

Thank you very much in advance

Mauricio
