Habr, hello! On the last day of June, our analyst meetup took place. It was attended by speakers from Leroy Merlin, Ostrovok.ru and, of course, Avito. We discussed regional A / B tests, managing the delivery of goods in a large online store, predicting profit from new features and data science in delivery.
Under the cut - video recordings of performances with timecodes and links to presentations.
Regional A / B tests. Why are we needed and how are they arranged - Igor Krasovsky, Avito
Using the example of problems from Avito, Igor told what regional A / B tests are, when an analyst needs them, what algorithms and mathematics are at their basis and how to measure the accuracy of these algorithms.
