Burnham and Anderson [1] recommend using AICc when n/K < 40.  But what do I consider for n?  The logistic regression is based on 2811 observations (334 trees observed annually for <= 10 yr), but I've only observed 32 deaths.  Harrell [2] would consider 32 to be the "limiting sample size" for determining the feasible number of predictor variables.  Is AIC the same?  Should I use 2811, 334, or 32 to figure out AICc?

  Great question.  I think I would probably go with 32, but I'd like to 
hear other opinions.
