About

I’m Dr. Christoph Pfeiffer. This is my personal notebook on applied quantitative methods — econometrics, data science and game theory, worked through in R and Python with a bias toward reproducible, honest analysis.

The through-line is simple: take a real method, apply it to real data, and show every step.

Professionally I work on strategic negotiation and procurement optimization through game theory at competitio. This blog is personal and separate from that work.
