[R] Nested AIC

[Aaron MacNeil]

Greetings,
I have recently come into some confusion over weather or not AIC  
results for comparing among models requires that they be nested.   
Reading Burnham & Anderson (2002) they are explicit that nested  
models are not required, but other respected statisticians have  
suggested that nesting is a pre-requisite for comparison.  Could  
anyone who feels strongly regarding either position post their  
arguments for or against nested models and AIC? This would assist me  
greatly in some analysis I am currently conducting.
Many thanks,

Aaron
