Hello: I would need some help on the use of RVM in the kernlab package. Questions: 1. Is there an optimal ratio between available number of cases and number of vectors? 2. Does something like "overfitting" exist? If so how can be detected/avoided? 3. The RVM model obtained is a S4 object. How can be saved and used in another session? Can it be exported as a C or VisualBasic file? Thank you very much Zack Holmes [[alternative HTML version deleted]]
