Bayesian Methods

Category: Science & Research  ·  Sub-category: math-stats  ·  Last updated:
Bayesian approach to statistical inference and decision-making. Covers prior specification, likelihood functions, posterior computation, conjugate priors, Markov chain Monte Carlo (MCMC), credible intervals, Bayesian hypothesis comparison (Bayes factors), hierarchical models, and the philosophical contrast with frequentist methods. Use when updating beliefs with data, specifying priors, computing posteriors, comparing Bayesian and frequentist approaches, or building hierarchical models.

About this skill (catalog notes)

How Bayesian Methods fits the catalog

Bayesian Methods sits in the Science & Research category under the math-stats sub-topic in the ClaudSkills catalog. There are 10 related skills indexed alongside it; comparing a few before installing usually reveals which fits your workflow best.

These notes are auto-generated from features detected in the SKILL.md file and from this catalog's structure — they aren't part of the source repository.

From the source SKILL.md

Bayesian statistics treats probability as a measure of belief, updated by data through Bayes' theorem. Where frequentist statistics asks "how likely are these data under H_0?", Bayesian statistics asks "given these data, what should I believe about the parameter?" This skill covers the machinery of Bayesian inference from prior specification through MCMC computation.

What this skill does

Bayesian Methods is a community-contributed Claude Code skill in the math-stats sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/bayesian-methods/ and loads when your prompt matches the skill's trigger.

When to invoke it: Use when updating beliefs with data, specifying priors, computing posteriors, comparing Bayesian and frequentist approaches, or building hierarchical models.

Who uses this skill

The Bayesian Methods Claude Code skill is built for researchers, data scientists, academics, and analysts working with complex data and scientific literature. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 116,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).

Frequently asked questions

How do I install the Bayesian Methods Claude Code skill?
Install via the ClaudSkills desktop app (one click) or copy SKILL.md from the source repository to ~/.claude/skills/bayesian-methods/SKILL.md and restart Claude Code. Both flows are detailed at claudskills.com/install/.
What does the Bayesian Methods skill do?
Bayesian approach to statistical inference and decision-making. Covers prior specification, likelihood functions, posterior computation, conjugate priors, Markov chain Monte Carlo (MCMC), credible intervals, Bayesian hypothesis comparison (Bayes factors), hierarchical models, and the philosophical contrast with frequentist methods. Use when updating beliefs with data, specifying priors, computing posteriors, comparing Bayesian and frequentist approaches, or building hierarchical models.
Is this skill free to install?
Yes. ClaudSkills is an open registry — every skill keeps its source repository's license, and manual install via copy is free. ClaudSkills Pro ($9/mo, $79/yr, or $149 one-time) adds one-click install via the desktop app and a multi-signal Quality Score.
When should I use the Bayesian Methods skill?
Use Bayesian Methods when your Claude Code task falls under the Science & Research category — specifically in the math stats area. Claude Code auto-discovers installed skills and invokes the right one based on the task description, so you can also ask Claude directly (e.g. "use Bayesian Methods" or describe the task and let Claude pick). Browse related skills at /category/science/.
What is a Claude Code skill and how does the Bayesian Methods skill fit in?
A Claude Code skill is a SKILL.md file that lives under ~/.claude/skills/<name>/ and tells the Claude Code CLI agent how to perform a specific task (instructions, prompts, allowed tools). Skills are auto-discovered at session start. Bayesian Methods is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the Science & Research category.
