Integration for Nonlinear Models with Lots of Random Effects
Over the last few years I’ve been getting more interested in how to deal with high dimensional integration of random effects. In straightforward nonlinear mixed effects models¹ you typically try to approximate a random effect by numerical integration. The standard…
Modeling Ordinal Change over Time
Say that you want to model ordinal change in status (e.g. a Likert scale) over time between two or three time periods. How do you go about it? I had to put a decent amount of thought into this problem…
