Combining Evidence Across Filtrations Using Adjusters

What's Game-Theoretic About Statistics? A Game-Theoretic Notion of Evidence and Cooperative Skepticism

[New blog post!] A gentle, (mostly) non-technical introduction to game-theoretic statistics, e-values, and my recent paper with Aaditya Ramdas on combining evidence across asymmetric information sets. Originally posted in the UChicago Data Science Institute Blog.
