Structural Bayesian Techniques for Experimental and Behavioral Economics
A book about estimating models from experimental economics datasets
papers.ssrn.com
My book is now available as a PDF here: papers.ssrn.com/sol3/papers....
It will still always be available in HTML (here: jamesblandecon.github.io/StructuralBa...), and HTML will be my preferred version (the tables look better).

Weird question: For strategy frequency estimation (SFEM), does anyone have a fast way to code up how many times a participant has followed a strategy? This is really easy for (say) memory-1 strategies, but for strategies with more than 2 states I can't see the matrix wrt doing it fast

I have added another experiment to the meta analysis, bringing it to a total of eleven experiments.
