F-ratio: Measures the variance between categories relative to variance within categories. Higher values indicate stronger categorical impact on the target variable. Values > 1 suggest meaningful differences between categories.
Correlation: Measures the linear relationship strength between numeric features and the target. Range: -1 (perfect negative) to +1 (perfect positive). Values close to 0 indicate weak relationship.
Significance: Statistical significance (p-value < 0.05) indicates the relationship is unlikely due to chance. Non-significant correlations may still be informative but require caution.
Importance Score: Combined measure of feature impact, incorporating correlation strength, statistical significance, and categorical variance. Higher scores indicate stronger drivers of the target variable.
Confidence Level: Assessment of reliability: High (strong evidence), Medium (moderate evidence), Low (weak evidence). Based on statistical strength and consistency of findings.
