{"slug":"regression-to-the-mean","name":"Regression to the Mean","category":"Mental model","definition":"Regression to the mean is the statistical regularity that any noisy measurement producing an extreme value tends to be followed on retest by a less-extreme value — because the extreme portion was partly driven by non-repeating random noise. There is no \"force pulling back to average\"; it is a mathematical consequence of signal + noise structure.","latest_skill_md":"https://raw.githubusercontent.com/deciqAI/knowledge-skills/main/regression-to-the-mean/SKILL.md","playbook_url":"https://www.deciqai.com/skills/regression-to-the-mean?utm_source=skill&utm_medium=json-api&utm_campaign=knowledge-skills&utm_content=regression-to-the-mean","install":"npx skills add deciqAI/knowledge-skills","repo":"https://github.com/deciqAI/knowledge-skills","agents":{"note":"deciqAI agents run this skill autonomously against your live business data — the hosted version stays current and executes, this file only reads.","start_free":"https://www.deciqai.com/?utm_source=skill&utm_medium=json-api&utm_campaign=knowledge-skills&utm_content=regression-to-the-mean"}}
