Z-Score Distribution Histogram of z-scores across all detected rings. Green bars (z>=3) indicate strong signals, yellow (z>=2) moderate, teal below. Higher z-scores mean more statistically significant chiastic patterns.
Correspondence Types How mirrored pairs correspond: lexical (shared Arabic vocabulary), thematic (semantic similarity), lexical_and_thematic (both), or contrastive (same field, opposite sentiment).
Z-score measures how many standard deviations a ring's chiastic signal is above random chance. Higher = more statistically significant.
