Training by practitioners
who ship real code.
Every trainer at stat4decision is an active data scientist or consultant. They solve production problems, then teach what they've learnt. No theoretical slides — only applied, tool-first learning built around your team's actual stack.

delivery formats
Three ways to train with us
All formats use the same trainers, the same materials and the same open-source stack. Pick what fits your organisation.
Sessions run on fixed dates at our Paris location. Max 7 participants — enough for discussion, small enough for individual follow-up. Ideal if you have 1–3 people to train.
We come to your site. Dates agreed with you. Content adapted to your tools, your data and your business context. Max 8 participants. Priced per session — cost-effective for larger teams.
Full live training via videoconference. Same hands-on approach — participants work in shared coding environments. Available for both open-enrolment and in-house formats.

What makes the difference
Training is only useful if participants can apply it immediately. Everything we do is optimised for that.
uv), R (with renv), and open LLMs. Environments are reproducible lockfile-based — participants can recreate them months later, on any machine.practicalities
What to expect
Small groups mean participants can ask questions freely and get individual help during exercises. We cap all sessions strictly.
Open-enrolment sessions. In-house: 9:30–13:00 and 14:00–17:30. Confirmed 3 weeks before with location and materials link.
Participants need a laptop. Loaner machines available on request for open-enrolment sessions. Setup guide sent in advance — environment takes 5 minutes with uv or renv.
Slides, notebooks and exercises on a secure participant platform. Code and additional materials on GitHub. Everything is available after the session — indefinitely.
Credit card (via PayPal link), bank transfer on purchase order, or direct OPCO billing. Registration up to the working day before, but 1 month recommended for OPCO processing.
