Consumer Lifetime Value Estimation

Duration
~25 minutes
Difficulty
Hard

You need to estimate consumer lifetime value (LTV) from first 30 days of behavior. This model will inform acquisition spend, retention investment, and growth strategy. The challenge: early behavior is noisy, promotional effects inflate initial usage, and different customer segments have wildly different trajectories.
