In comparing 2 GAM models are there some guidelines to determine which model
might be a better fit by comparing the 2 UBRE scores?  I assume that a
larger value is indicative of a better fit? What magnitude of difference is
a significant one?  I imagine that one could also use the percent of
explained deviance.  Is that a reliable statistic?  Are there any other
statistics that one would use for model selection?
