Production MMM breaks when influencers aren't interchangeable, campaigns shift, and channels enter mid-series.
Part III of our Nürnberger case study tackles all three. 27%+ CPL reduction:

We're sponsoring the M-Agents Hackathon at #NYCTechWeek on June 7.
Go from zero to a working multi-agent AI system in one day, built with open-source tools like #PyMC and Decision Lab.
Winners get a seat in our Agentic AI course.
Spots are limited https://t.co/LD9I6ADKyx
When your MMM ignores funnel dynamics and budget caps, upper-funnel channels look like they underperform. They don't.
Part II of our Nürnberger case study shows how a censored-likelihood Bayesian MMM fixes it https://t.co/DfDecIC0yj

@Wegmans needed to quantify cannibalization risk before opening new stores. We built a Bayesian system that answers in minutes, not weeks.

We replaced a PyMC compiler with an LLM agent that transpiles to Rust. 3-7x faster sampling, validated against reference gradients, ~500 lines of scaffolding.

"How many people did COVID kill in the UK?" is the wrong question.
The right one is counterfactual: how many would have died without it?
You can't observe that world. You have to model it.

I want to use AI agents, but I can't trust the output."
We kept hearing this, so we built a community to solve it together. Daily AI news briefs, early tool access, and real conversations.

Why do women outlive men by 12 years in some countries but only 2 in others? @AllenDowney breaks it down with Bayesian counterfactual modeling, live at @_odsc East, April 30.

Why does LASSO shrink every sector's coefficient toward zero, whether momentum, value, or profitability?
Wrong target. Partial pooling in #PyMC shrinks to a learned global mean instead. Net Sharpe 1.47 on US equities after costs

Getting an LLM to run an analysis is easy. Getting it to run one you'd stake a decision on? Different problem entirely.

Equity markets cycle through regimes (low-vol trends, selloffs, grinds), each with different return profiles.
Averaging across them fits a market that never existed. Bayesian HMM in PyMC. 94% regime detection accuracy.

Your optimization model is only as good as the forecast you feed it.
We partnered with @FICO_corp to show what happens when you replace point estimates with full distributions. The results changed the decisions, not just the forecasts.
