st: AIC for Mixed-Effects Models

[Chris Johnson <johnsoch@unbc.ca>]

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
