All examples for Correlation Matrix Generator

Real Estate Property Correlation Matrix

Generating correlation matrix for housing dataset with property features (sqft, bedrooms, bathrooms, lot_size, year_built) and sale price. Shows realistic correlations between size metrics and price, with multicollinearity warnings for regression preparation.

============================================================
CORRELATION ANALYSIS RESULTS

Dataset: 400 rows x 6 columns
Numeric variables analyzed: 6
Variables: sqft, bedrooms, bathrooms, lot_size, year_built, price

Strong Correlations Found: 7 (|r| > 0.7)

sqft ↔ price r = 0.980 (positive)
sqft ↔ bedrooms r = 0.838 (positive)
lot_size ↔ price r = 0.832 (positive)
bedrooms ↔ price r = 0.826 (positive)
sqft ↔ lot_size r = 0.807 (positive)
bathrooms ↔ price r = 0.770 (positive)
sqft ↔ bathrooms r = 0.763 (positive)

Multicollinearity Issues: 5 (|r| > 0.8)

WARNING: High correlations detected between predictors!
Consider removing or combining these variables for regression modeling:

  • sqft <-> price (r = 0.980)
  • sqft <-> bedrooms (r = 0.838)
  • lot_size <-> price (r = 0.832)
  • bedrooms <-> price (r = 0.826)
  • sqft <-> lot_size (r = 0.807)
