Nothing
Power analysis for AB testing. The calculations are based on the Welch's unequal variances ttest, which is generally preferred over the Student's ttest when sample sizes and variances of the two groups are unequal, which is frequently the case in AB testing. In such situations, the Student's ttest will give biased results due to using the pooled standard deviation, unlike the Welch's ttest.
