 ## Test Coverage
 
-The integration tests cover the following analysis modules:
-
-- **Cohort Analysis** - Tests customer cohort retention metrics
-- **Cross Shop Analysis** - Tests product/category cross-shopping patterns
-- **Customer Analysis** - Tests customer lifetime value and purchase frequency metrics
-- **Gain Loss Analysis** - Tests comparative performance analysis
-- **Haversine Analysis** - Tests geographic distance calculations
-- **Product Association Analysis** - Tests market basket analysis
-- **Customer Decision Hierarchy** - Tests customer purchase decision patterns
-- **Revenue Tree Analysis** - Tests hierarchical revenue breakdowns
-- **Composite Rank Analysis** - Tests weighted ranking of entities
-- **Segmentation Analysis** - Tests RFM and value-frequency customer segmentation
+The integration tests cover the analysis modules.
