[R] R & gams

[Ravi Varadhan]

Can you be more specific about what you mean by "gams"?  Do you mean
generalized additive models (GAM)?  If so, R is a good environment for
forecasting models and GAM.  However, the link that you provided is NOT for
generalized additive modeling, but it is for General Algebraic Modeling
System (GAMS), which is a high-level modeling system for mathematical
programming and optimization.

Ravi.

Subject: [R] R & gams

At office I have been introduced by another company  to new, complex energy 
forecasting models using gams as the basic software.
I have been told by the company offering the models that gams is specialised

in dealing with huge, hevy-weight linear and non-linear modelling (see an 
example in http://www.gams.com/modtype/index.htm) and they say it is almost 
the only option for doing it.

I would like to know your opinion on the subject and, above all, if R can be

an effective alternative and to what extent, if any.

Thanks
Vittorio
