Bolker’s Reanalysis of Owl Data

Hi class,

Here is an interesting example from Ben Bolker using the owls dataset.   He shows how to use an observation level group effect (to effectively change to a Poisson-lognormal distribution), how to predict the expected values of a lme4 model, and an interesting way to plot expected vs. observed with confidence intervals.  I might have to learn ggplot2! Enjoy!

Here are the pdf and the script I did in class:
