1. The Quest to Understand Metric Movements
Stories by Pinterest Engineering on Medium
📣️ newtler Comments
This resource is valuable for anyone trying to understand fluctuations in key metrics.
📄 Summary
It outlines three approaches for root-cause analysis of metric movements: Slice and Dice, General Similarity, and Experiment Effects.
The Slice and Dice method involves breaking down metrics into segments to identify significant contributors to changes.
General Similarity examines correlations between metrics to find related movements, while Experiment Effects analyzes the impact of A/B tests on metrics.
