Alex Andorra & Jesse Grabowski talk about state space models, simplifying forecasting, applications etc.

I genuinely miss PyMC2. The #PyMC and #Arviz APIs changes so frequently, that it's impossible to know what the standard approach to anything is.

#Bayesian #Statistics in #Python should be easy.

To be honest, I'd really like a well maintained #SkLearn module for it.

Learning about PyMC makes me want to become a statistician.. super interesting way to think about data, but so much goes into building a good model! So many rabbit holes.

Bayesian modelling is clearly super powerful though and seems to offer some answers to some of the most intractable problems with black-box ML. A reliable model with known and understandable inputs is invaluable for certain use cases.

Cohort Revenue & Retention Analysis with Python

For those who work with cohort data, I recommend checking Dr.Juan Orduz tutorial for cohort revenue and retention analysis with PyMC

https://www.pymc-labs.com/blog-posts/cohort-revenue-retention/

So testing some intuition on moving a deterministic analysis into a complex #Bayesian inference problem using #PyMC has been a really fast process. I'm very impressed with how easy it's been to use it. Well chuffed!!!

Did you know that @pymc has a backend enabling live streaming of MCMCs to a #ClickHouse database?

Check out https://github.com/pymc-devs/mcbackend to learn more about #McBackend, and visit https://github.com/pymc-devs/pymc/wiki/GSoC-2024-projects#Extending-McBackend-related-features if you're interested in doing a Google Summer of Code project on this! #PyMC #GSoC #GSoC2024

Introducing "@as_model" in PyMC-Experimental API!

Key Features:
- Simplifies PyMC modeling
- Better code structure

Details: GitHub PR #268 https://github.com/pymc-devs/pymc-experimental/pull/268

Thanks to Theo Rashid, @ricardoV94, Rob Zinkov, @twiecki and Maxim Kochurov !

Modern #Bayesian samplers like #PyMC are too fast... no way to take a break and having the impression to get things done in parallel... barely the time to toot.

At the encouragement of @nkaretnikov I made a blogpost on how to use #pymc in a more functional style!

The PyMC community team will be holding office hours to provide an outlet for the community to ask questions, get help, discuss, etc. Office hours are open to everyone, and anyone should feel welcome to attend

Date: Wednesday, 1st Nov, 2023
Time: 19 UTC / 12 pm PT / 3 pm ET
Where: Online, on Zoom
Register (for Zoom link): https://www.meetup.com/pymc-online-meetup/events/296914851/

Office hours will last about an hour, so don't worry if you can't make it at exactly this time! see you there
