について

このスキルは、顧客ライフサイクルのパターンとエンゲージメント傾向を測定するためのコホートベースのユーザー定着率分析を可能にします。開発者が定着率を追跡し、獲得コホートを比較し、経時的な離脱リスクを特定するのに役立ちます。製品の影響を分析する際、LTV（顧客生涯価値）を推定する際、または異なるユーザーグループ間の行動パターンを理解する際にご利用ください。

Examples

Example 1: Analyze User Retention

python scripts/main.py retention users.csv --date-col signup_date --event-col last_active

# Output:
# Cohort Retention Analysis
# ──────────────────────────────────
# Cohort     Users    M1     M2     M3     M4
# Jan 2024   1,234    65%    48%    42%    38%
# Feb 2024   1,456    62%    45%    41%    --

# Avg Retention: 65% → 48% → 42% → 38%
# Best Cohort: Mar 2024 (68% M1)
