PM wants to ship: A/B test shows +6% conversion at p=0.04 after peeking daily for two weeks. Do I sign off?

CLAUDE · AS LEILA, DATA SCIENTIST No - daily peeking at p=0.04 is how false positives ship; with 14 looks your effective alpha is closer to 0.2 than 0.05. Rerun the readout properly: fixed horizon at the pre-registered sample size, or sequential testing with alpha spending if the org insists on watching daily. Check SRM first - if the split isn't 50/50 within noise, the test is invalid regardless of p. And +6% with what interval? If the CI reads [0.2%, 12%], say it out loud. Send me daily counts per arm and I'll give you the honest readout.

Questions about this product

What does the Leila skill do?+

Do rigorous data science: EDA, statistics, A/B test design and analysis, modeling and causal reasoning. Load it once into Claude Projects and you get a configured Data Scientist without re-explaining context at the start of every session. Always develop and validate against a held-out sample in a dev or staging environment, version your data, code and models, and review before running against production data or serving a model in production.

How do I install this skill file?+

Download the .skill package (it contains SKILL.md), paste the contents into Claude Projects Instructions or your AI's system prompt, add your own context and start your first session. Works with Claude, ChatGPT, or any AI chat that accepts system prompts.

Which AI tools does this skill work with?+

Works with Claude (recommended), ChatGPT, Gemini, Perplexity and Copilot, and any AI chat that accepts system prompts. Claude Projects gives the best results.

What is included in this download?+

One .skill package delivered instantly after purchase: the full SKILL.md role configuration plus a worked-example file with a real scenario so you see the quality before you rely on it. No subscription, yours permanently.

How is this different from using Claude without the Leila skill?+

Without a skill file your AI starts every session as a general assistant. With Leila loaded it applies Data Scientist methodology from the first message, with consistent quality every time. Always develop and validate against a held-out sample in a dev or staging environment, version your data, code and models, and review before running against production data or serving a model in production.

Do I have to read it myself?+

No. The file is written for your AI to read, not for you. Upload it or paste it in once and the AI takes on the role. After that you just ask it questions the way you normally would. You're welcome to open it and read it, but nothing here depends on you doing that.

Is this a physical book?+

No, it's digital. You download it the moment the order goes through and it's yours permanently. The cover is styled like a book because each edition is written and edited as one self-contained piece of work. The reading part is your AI's job, not yours.
