New Sequential Testing Capabilities

Sequential Testing

Today, we’re continuing to invest in our Stats Engine with the addition of Sequential Testing capabilities. In Sequential Testing, the p-values for each preliminary analysis window are adjusted to compensate for the increased false positive rate associated with peeking. The goal is to enable early decision-making when there's sufficient evidence, while limiting the risk of false positives.

To enable Sequential Testing on your experiment, we require setting a target duration (which is used to calculate the adjusted p-values). We provide a handy Power Analysis Calculator within Experiment Setup to enable quick and easy estimation of target duration.

Once a target duration is set, simply toggle on Sequential Testing to start seeing adjusted confidence intervals overlayed over the default 95% confidence interval within your Pulse results.

At Notion, we're continuously learning what our users value and want every team to run experiments to learn more. It’s also critical to maintain speed as a habit. Statsig's experimentation platform enables both this speed and learning for us.

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.
