to the problem we would have if the models were viewed as
regular mixed models and we tried to use a GLRT to test variance
components for equality to zero).
These issues are now documented in ?anova.gam and ?summary.gam...

against my intuition.

decrease of the degrees of freedom invested by the
total model (caused by a decrease of the edf's of splines in the model
with the interaction). In this case, how would I proceed in
determining if the model including the interaction term is better?

Dear useRs,
I have used using the excellent mgcv package (version 1.7-12) to
create a generalized additive model (gam) including random effects -
represented with s(...,bs=re) - on the basis of dialect data.
My model contains two random-effect factors (Word
, and/or ii) how I can link the random slopes which are
present to the correct labels of the words?
(I did not include the model as it is 300 MB in size, but let me know
if this is necessary.)
Any help would be greatly appreciated!
