Update: Marco Pinto and Hernando Ombao made a much nicer interface to the model, which I recommend instead of my original version (still linked below).
As a follow up to this series of posts, I’ve created a version of the model that you can experiment with on your own, without needing to know any computer programming. Try it here.
Note that it may take some time for the model to load.
If you arrived here and haven’t already read the series of posts on this topic, I recommend that you start at the beginning.
