Does CUPED Adjust for Pre-Experiment Bias in Metrics?
Date of slack thread: 5/25/24
Anonymous: Hi, we are running an experiment that shows significantly worse results for several metrics with CUPED turned on than with it turned off. How should we interpret this? Does this indicate that CUPED is able to remove some pre-experiment bias that is making those metrics look positive when it is off?
Lin Jia (Statsig): Bot is right. Our Data team has a blog with full details and quantitative results: https://www.statsig.com/blog/cuped

We evaluated Optimizely, LaunchDarkly, Split, and Eppo, but ultimately selected Statsig due to its comprehensive end-to-end integration. We wanted a complete solution rather than a partial one, including everything from the stats engine to data ingestion.
