Accuracy through Stats Engine and flexible data
Optimizely’s Stats Engine provides real-time sequential statistics to deliver accurate results, fast. At any time, you can look at the results page and see experiment status live without incurring a peeking error, which means that given sufficient traffic, you can reach statistical significance within hours. Additionally, our machine learning allocation can accelerate reaching significance for ABn tests.
To alleviate concerns about interaction effects, Stats Engine has built in error controls for multiple comparisons, and lets you use exclusion groups when multiple experiments are running.
For data professionals and analysts, Enriched Events Export can connect to your analytics platform, while our data services offer a way to analyze experiment data with other sources and alternative statistical methods.
