| Subject | st: AIC for Mixed-Effects Models |
| Date | Tue, 02 Nov 2010 20:55:34 -0700 |
Hello all.I am using GLLAMM to fit a relatively simple mixed effects model with a random intercept for individual (gllamm tracks2 sex distperday2, i(otterid) link(logit) family(bin) robust adapt). I want to use a model selection strategy based on AIC, but I am struggling with the calculation of p as presented in Vaida and Blanchard (2005) or more recent papers (e.g., Liang et al. 2008). I am hoping for guidance on the calculation or a do file to automate the process.
Thanks much, Chris -- Chris Johnson Associate Professor Ecosystem Science and Management Program University of Northern British Columbia Prince George, BC V2N 4Z9 ------------------------------------------------ Phone: 250-960-5357 Email: johnsoch@unbc.ca http://web.unbc.ca/~johnsoch/ * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
