# Impact analyses

Build an impact analysis in Hypertune to see the impact of an experiment on multiple metrics in a single view.

Choose between:

* **Frequentist analysis** — shows you conversion rate uplift with confidence intervals
* **Bayesian analysis** — shows you the probability of each variant being the best

Both methods automatically apply adjustments for:

* **Sequential testing** — avoids the **peeking problem**, enabling you to view results at any time and ship a variant if it has a significant result
* **Multiple comparisons** — adjusts for the **family-wise error rate**, enabling you to compare more than two variants (in a multi-arm test), to determine an overall winner
