%description
Power analysis for AB testing. The calculations are based on the Welch's
unequal variances t-test, which is generally preferred over the Student's
t-test 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 t-test will give biased results due to using the pooled standard
deviation, unlike the Welch's t-test.
