Hi Minda, AIC scores depend upon the statistical models used. I think R does the best job of providing these scores, for example in the context of multiple linear regression and generalized linear models.
The literature on R or on stats using R is growing rapidly. You will find readable treatments of AIC in Crawley's 2007 R book or in Zuur et al'sv2009 Mixed Effects Models and extensions in Ecology with R. And do not forget to examine ( I am not sure read is a realistic option) the valuable book by Burnham and Anderson 2002, Models Selection and Multimodel Inference.

I've looked into the AICcmodavg package with R, but the associated instructional material is not clear and I have not been able to get it to work. I hear that SAS is good as well, but have not found a good book that tells me how to create AIC scores (recommendations would be appreciated). I've also looked into SPSS, which according to IBM can create AIC scores, but have had no success. Any recommendations for programs and clear associated instructional material with information on how to run the program, write the code etc. would be greatly appreciated. Thanks, Minda Berbeco Viticulture and Enology, UC Davis [email protected]
