Dear all, Using the quasibinomial and quasipoisson families results in no AIC being calculated. However, a quasi AIC has actually been defined by Lebreton et al (1992). In the (in my opinon, at least) very interesting book by Burnham and Anderson (1998,2002) this QAIC (and also QAICc) is covered. Maybe this is something that could be implemented in R.
Take a look at page 23 in this pdf: http://www.springer-ny.com/supplements/0387953647/Preface_Contents_and_Chapter_8.pdf Lebreton, J-D et al. (1992) Modeling Survival and Testing Biological Hypotheses Using Marked Anomals: A Unified Approach with Case Studies. Ecological Monographs, 62(1), 67-118. Burnham, K.P. & Anderson, D.R.
