# Contribution Analysis Guide

## Overview

Contribution analysis quantifies how much each factor contributes to explaining the variance of a response variable. This skill focuses on R² decomposition method.

## Complete Workflow

When you have multiple correlated variables that belong to different categories:
```python
import pandas as pd
import numpy as np
from sklearn.preprocessing import StandardScaler
from sklearn.linear_model import LinearRegression
