  1. 1. SEQUENTIAL A/B TESTING USING PRE-EXPERIMENT DATA

    University essay from Uppsala universitet/Statistiska institutionen

    Author : Erik Stenberg; [2019]
    Keywords : A B testing; sequential analysis; continouous monitoring; variance reduction;

    Abstract : This thesis bridges the gap between two popular methods of achieving more efficient online experiments, sequential tests and variance reduction with pre-experiment data. Through simulations, it is shown that there is efficiency to be gained in using control-variates sequentially along with the popular mixture Sequential Probability Ratio Test. READ MORE

  3. 2. On numerical simulations of turbulent flows subjected to system rotation

    University essay from KTH/Mekanik

    Author : Erik Stenberg; [2016]
    Keywords : ;

    Abstract : Different aspects of numerical simulations of turbulent flows are assessed by considering a fully-developed turbulent channel flow that is rotating in the spanwise direction. Differences between differential and explicit algebraic Reynolds-stress models (RSMs) are investigated theoretically and numerically. READ MORE

  6. 5. Kartläggning av långbensgroda Rana dalmatina på Öland - med rekommendationer för biogeografisk uppföljning

    University essay from Lunds universitet/Examensarbeten i biologi

    Author : Erik Fridolf; [2014]
    Keywords : Biology and Life Sciences;

    Abstract : As a result of e.g. habitat loss and diseases, a global decline of amphibians is a fact. In order to prevent further declines and to improve the conservation status for amphibians in Europe, the member states have to report the status for amphibians every sixth year to EU. READ MORE
