On July 15, Kolesa Online Analytics Meetup will be held online
You can't fool Holdout: why a successful test is not a victory yet
At the meeting, we will analyze the real case of the full life cycle of the experiment — from the hypothesis and the successful statistical test to the rollout of the feature to the entire audience. Let's tell you how a month later the holdout group showed that the feature would have to be rolled back.
Speaker: Kamila Bishenova, Data Analyst, Kolesa Group.
