Features

• Cohort Retention Triangles: Calculates multi-period retention matrices and average longitudinal survival curves.
• Granger Causality Testing: Computes F-statistics to rigorously verify whether feature adoption causes retention gains.
• Churn Hazard Inflection: Pinpoints exact customer drop-off days to trigger proactive customer success playbooks.

Quickstart

from client import GenParkGrowthDataAnalyst

analyst = GenParkGrowthDataAnalyst()
cohorts = [{"cohort": "2026-01", "cohort_size": 100, "active_users": [100, 50, 40]}]
res = analyst.build_cohort_retention_triangle(cohorts)
print("Avg Retention:", res["average_retention_curve_pct"])
