And presumably each of the predict, residial and standard_error
members should be functions returning a vector of doubles?  What would
their inputs be? I think also a vector of doubles.  

I think I've read that all models can be represented by the
second formula (the unnumbered one) --- in fact I think it can be
simplified slightly.  Does that fit with your view?

If not, then I suppose a model would have to be defined recursively by
a "composite" data type (see "Design Patterns" by Gamma et al.).
