What it does

Performing Regression Analysis is an agent skill from jeremylongshore/tons-of-skills-marketplace. Execute this skill empowers AI assistant to perform regression analysis and modeling using the regression-analysis-tool plugin. it analyzes datasets, generates appropriate regression models (linear, polynomial, etc.), validates the models, and provides performa... Use when analyzing code or data. Trigger with phrases like 'analyze', 'review', or 'examine'.

Its SKILL.md is about 940 tokens, which your agent loads only when the skill is triggered. The skill folder holds 11 other files, including scripts, reference files and assets (for example `assets/README.md`, `assets/model_visualization_template.py` and `references/README.md`). Compatibility notes: Designed for Claude Code

It sits in Data & Analytics, covering Statistics and Machine learning. The repository describes itself as: Model-agnostic agent-skills platform with a harness-free canonical layer, verified adapters, and the ccpi package manager. Explore at tonsofskills.com. The licence is MIT.

When your agent uses it

  • With phrases like analyze
  • Tasks that involve Statistics
  • Tasks that involve Machine learning

Example prompts

  • “analyze”
  • “review”
  • “examine”
  • “/performing-regression-analysis”

Requirements

  • Python 3
  • Compatibility (from SKILL.md): Designed for Claude Code
  • Pre-approved tools (allowed-tools): Read, Write, Edit, Grep, Glob, Bash(cmd:*)

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. Data Analysis: Claude analyzes the provided data to understand its structure and identify potential relationships between variables.
  2. Model Generation: Based on the data, Claude generates appropriate regression models (e.g., linear, polynomial).
  3. Model Validation: Claude validates the generated models to ensure their accuracy and reliability.
  4. Performance Reporting: Claude provides performance metrics and insights into the model's effectiveness.

What it can do on your machine

Read from SKILL.md and the folder at commit cfae287. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Read
    • Write
    • Edit
    • Grep
    • Glob
    • Bash(cmd:*)

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 4 files in scripts/ (Python), which the agent can run.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

  • Compatibility

    Designed for Claude Code

    From compatibility in the SKILL.md frontmatter.

Context cost

Performing Regression Analysis loads about 944 tokens when it runs, and up to ~961 if it reads all its reference files. Until then it costs about 97 tokens; SKILL.md has 423 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~97
When it runs · the whole SKILL.md, loaded when a task matches
~944
With references · SKILL.md plus every file in references/, read only if the agent opens them
~961

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

Regression Analysis Tool

Perform regression analysis by building and validating linear, polynomial, and other regression models to uncover variable relationships and predict continuous outcomes.

Overview

analyze data, build regression models, and provide insights into the relationships between variables. It leverages the regression-analysis-tool plugin to automate the process and ensure best practices are followed.

How It Works

  1. Data Analysis: Claude analyzes the provided data to understand its structure and identify potential relationships between variables.
  2. Model Generation: Based on the data, Claude generates appropriate regression models (e.g., linear, polynomial).
  3. Model Validation: Claude validates the generated models to ensure their accuracy and reliability.
  4. Performance Reporting: Claude provides performance metrics and insights into the model's effectiveness.

When to Use This Skill

This skill activates when you need to:

  • Perform regression analysis on a given dataset.
  • Predict future values based on existing data using regression models.
  • Understand the relationship between independent and dependent variables.
  • Evaluate the performance of a regression model.

Examples

Example 1: Predicting House Prices

User request: "Can you build a regression model to predict house prices based on square footage and number of bedrooms?"

The skill will:

  1. Analyze the provided data on house prices, square footage, and number of bedrooms.
  2. Generate a regression model (likely multiple to compare) to predict house prices.
  3. Provide performance metrics such as R-squared and RMSE.

User request: "I need to analyze the sales data for the past year and identify any trends using regression analysis."

The skill will:

  1. Analyze the provided sales data.
  2. Generate a regression model to identify trends and patterns in the sales data.
  3. Visualize the trend and report the equation and R-squared value.

Best Practices

  • Data Preparation: Ensure the data is clean and preprocessed before performing regression analysis.
  • Model Selection: Choose the appropriate regression model based on the data and the problem.
  • Validation: Always validate the model to ensure its accuracy and reliability.

Integration

This skill works independently using the regression-analysis-tool plugin. It can be used in conjunction with other data analysis and visualization tools to provide a comprehensive understanding of the data.

Prerequisites

  • Appropriate file access permissions
  • Required dependencies installed

Instructions

  1. Invoke this skill when the trigger conditions are met
  2. Provide necessary context and parameters
  3. Review the generated output
  4. Apply modifications as needed

Output

The skill produces structured output relevant to the task.
