What it does
Run regression analysis (OLS or logistic) on uploaded CSV/Excel data, generating coefficients, R², p-values, VIF, and plain-language interpretation. Triggered by requests for regression modeling, fitting data, testing significance, checking multicollinearity, or keywords like OLS, logit, coefficient, p-value, or R-squared.
regression-modeler
Automated regression modeling tool, performs linear regression (OLS) or logistic regression (Logit) on tabular data, producing comprehensive statistical results with plain-language interpretation.
Capabilities
| Feature | Description |
|---|---|
| Linear Regression | OLS with coefficients, R², adjusted R², F-test, AIC/BIC, Durbin-Watson |
| Logistic Regression | Logit with coefficients, Odds Ratio, Pseudo R², likelihood ratio test |
| Multicollinearity Detection | VIF values for each predictor with warning levels |
| Plain-Language Interpretation | Clear explanations of what each metric and coefficient means |
| Auto Detection | Automatically switches to logistic regression when the target is binary (0/1) |
Quick Start
# Linear regression: predict price using all numeric columns as predictors
python3 scripts/regression_analyzer.py data.csv --target price
# Logistic regression: predict churn (0/1) with specified features
python3 scripts/regression_analyzer.py users.csv --target churn --features "age,income,tenure"
# Save results to JSON
python3 scripts/regression_analyzer.py data.csv --target sales --output result.json
Detailed Usage
Basic Invocation
python3 scripts/regression_analyzer.py <data_file> --target <target_column> [options]
Specifying Regression Type
# Force linear regression
python3 scripts/regression_analyzer.py data.csv -t y --type linear
# Force logistic regression
python3 scripts/regression_analyzer.py data.csv -t label --type logistic
# Auto-detect (default)
python3 scripts/regression_analyzer.py data.csv -t y --type auto
Selecting Feature Columns
# Manually specify (comma-separated)
python3 scripts/regression_analyzer.py data.csv -t price -f "sqft,bedrooms,bathrooms"
# Omit to automatically use all numeric columns
python3 scripts/regression_analyzer.py data.csv -t price
