A/B Testing: "Chance to Win" for Revenue Per User

Overview

Pack's A/B testing calculates a "Chance to Win" metric for each variant — the Bayesian probability that a variant outperforms the control. For revenue-based goals, this tells you the likelihood that a variant generates more revenue per user than the control.

The calculation happens in two stages:

1. BigQuery aggregates raw event data (total revenue, visitor counts, etc.) per variant
2. Bayesian Engine computes the probability that each variant beats the control
