Kudos to @sethaxen.com for implementing the Pyro wrapper that makes this possible (shipped in sbi v0.25)! And thanks to @juanitorduz.bsky.social sharing the cookie factory example—it's a great accessible example for hierarchical inference. Everything runs in Colab 📊

The ArviZ core devs have done tremendous work on an improved API with a lot of novel improvements. They have put together a great migration guide: python.arviz.org/en/stable/us... If you are an ArviZ user please take a look at it and provide feedback. Open source is all about the community 🫶

I’ll be giving a talk ok variational inference (VI) at PyData Berlin 2025 🙂! I’ll focus on some learnings of using VI for forecasting models at scale. If you are around come and say hi. #PyDataBerlin

I used to experience this and it is fucking horrible 🫠

A beautiful read! @markhoppus.bsky.social #blink182

Forecasting isn’t just about prediction — it’s about decision-making under uncertainty. @juanitorduz.bsky.social shows how Bayesian models help: 🔹 Sparse data? Use hierarchies 🔹 Stockouts? Use censored likelihoods 🔹 Messy demand? Use priors + state spaces Practical guide 👉 dub.sh/prob-forecas...

Freedom of science and research is one of Europe's great strengths. It’s how excellence and innovation thrive. We’ll make proposals to help scientists and researchers ‘Choose Europe’. The best and brightest from around the world.

Here is a first intro notebook on Bayesian Power Analysis following the method described in the paper "The Bayesian New Statistics: Hypothesis testing, estimation, meta-analysis, and power analysis from a Bayesian perspective" (link.springer.com/content/pdf/...) juanitorduz.github.io/power_sample...

Here is a new blog post with PyMC Labs: "Probabilistic Time Series Analysis: Opportunities and Applications." We provide a collection of business cases where probabilistic methods excel in real-world applications of probabilistic time series methods. www.pymc-labs.com/blog-posts/p...

I decided to wrap these cohort modeling techniques in a little pre-print 🤗 arxiv.org/abs/2504.16216

A new Python edition of "Forecasting: Principles and Practice" is now available online at otexts.com/fpppy/. Thanks to @azulgarza.bsky.social, Cristian Challu, Max Mergenthaler, Kin Olivares & Nixtla for making this happen. #forecasting #python

📚😅🎉 Yay!! I just submitted the complete manuscript of my upcoming book to the publisher! Learn to easily and clearly interpret (almost) any stats model w/ R or Python. Simple ideas, consistent workflow, powerful tools, detailed case studies. Read it for free @ marginaleffects.com #RStats #PyData

This is my current readingI had it in my mind for many years and I finally decided to read it! So far so good!

I’ll be attending the 3rd Vienna Workshop on Economic Forecasting 2025 where I will have a poster on “Probabilistic Forecasting at Scale with NumPyro” 🙂 www.ihs.ac.at/current/even...

At PyMC Labs I've been working with a group developing synthetic consumers for marketing research. We just published this white paper with an overview of work in this space -- and we have a blog post coming next week with some experimental results. www.pymc-labs.com/blog-posts/s...

We just launched our first white paper! By 2027, AI-generated consumers could power 50%+ of market research data. 📄 What’s inside? ✅ What synthetic consumers are ✅ How businesses use them and more.... 🔗 dub.sh/61AEavU 📩 Curious how this could benefit your org? 👉 [email protected] #GenAI

We just released PyMC-Marketing with a new multidimensional MMM class to allow for custom hierarchical model across multiple dimensions (e.g. geographies). You can specify hierarchical components easily so the opportunities are huge. www.pymc-marketing.io/en/stable/no... #mmm #pymc #marketing

Open source is draining. One's todo-list is open to world. People seldom realize the cost of what they get for free. Unpleasant comments do happen. Cost of maintenance is not understood. opensource.com/article/17/2...

It was suggested by @juanitorduz.bsky.social that I add some simulation proof to some claims I make in my blog post over at geteppo.com By all means, have some simulation proof (plus a little explanation of what I said re: pulling estimates apart) dpananos.github.io/posts/2025-0...

Hi! Here is a question for all the #bayesian folks! Can you recommend references on evaluation and diagnostics of (stochastic) variational inference? Anything would be much appreciated 🙏

PyMC-Marketing 0.11.0 is out! It is a huge release with more than 80 PRs from the community 🚀. Checkout the release notes: github.com/pymc-labs/py...

"Masculine Energy"

Its much more pleasant to write a latex article with a linter, git, girhub actions, and LLMs thank in a simple tex editor (10 years ago 😅)

We're looking to connect Berlin & Brandenburg researchers working with causal graphs from all disciplines! ➡️ "Direct" link: applied-causal-graphs.de ⬅️ ⏱️ Abstracts due Feb 7th! #CausalInference #DAGs #Berlin #CausalGraphs ⭐ Keynotes by @philippbach.bsky.social @pwgtennant.bsky.social & Simone Maxand

I hate everything about Meta 😒.

Classic Meta being Meta.

✨ This year, we saw many new contributors contribute to PyMC-Marketing & CausalPy. Their work has made a real difference. 🌱 Some are first-time contributors, while others are experienced developers. 🙏 Thank you to everyone who contributed this year we’re excited to see what’s next!

Working with together Claude and exploring JAX internals to write the demean step (alternating projections algorithm) for PyFixEst! The first experiments on GPU show potential against the current numba implementation. The PR is is still open for comments and feedback github.com/py-econometr...

I have decided to collect talk recordings and slides in the same place 🙃 juanitorduz.github.io/talks/

Yesterday I gave a summary talk on probabilistic forecasting: opportunities and applications Next year I’ll continue experimenting and sharing more around these topics 🙂 juanitorduz.github.io/html/paretos...

I have been using Pydantic for more than a year and Pandera for around 8 months for data validation and it has made my data workflow so much better! Totally recommended!

Here is an experiment on hacking the TSB model for intermediate time series to accommodate availability constraints. We provide a way to add availability constraints to forecast the "true" demand and avoid just predicting zeros. juanitorduz.github.io/availability...

I have a new paper out on #forecasting harms: arxiv.org/abs/2411.16531 with Bahman Rostami-Tabar, Travis Greene and Galit Shmueli.

I thought a forecasters starter pack might be useful, but I can't find many people. This is a start. Please suggest additions. go.bsky.app/NJJseT8

For those who don’t know yet, I am organising an online talk series together with Arno Solin on “Advances in Probabilistic Machine Learning (APML)”. It’s free for everyone to join and support early career researchers! You can register and check out the schedule here: aaltoml.github.io/apml/

PyMC developers & contributors starter pack go.bsky.app/VL7kEjd (let me know if I forgot to add you).

Starter pack for time series analysis and forecasting (at scale) ?

Any PyMC-Marketing users or curious about it? I would love to connect github.com/pymc-labs/py...

Finally deleted my Twitter account 🙌
