rw2diid using rgeneric

[jlg...@uw.edu]

Hi,

I have a couple questions regarding the RW2iid model. 

1) If i wanted to build a model with a rw2 effect in time and also an iid effect in time, can this be used for that? or is it only usable for space (and if this is the case, how does it differ from the bym2 implementation?)?

2) Is there a corresponding INLA:::rw() function for the rw2diid model?

Thanks,

there isn't a such model, but I guess you try to make one.

Hi, oops, yes i meant the RW2Diid.

A realization from the rw2diid model is smoother than one from the bym2
model.

If you like, you can try a bym2 for time, which will be a kind of
rw1diid. See the attached code example.
