    University essay from

    Author : Jacob Allestam; Filip Sjöberg; [2023-06-29]
    Keywords : Adaptive market hypothesis; market efficiency; market conditions; return predictability; trading strategy;

    Abstract : This study examines if the adaptive market hypothesis holds for the Swedish stock market between 1990 and 2019. We use Affärsvärldens Generalindex and test for time-varying return predictability by implementing a variance ratio test and an autocorrelation test. To track how market efficiency evolves over time we use a two-year moving subsample. READ MORE

  3. 2. MetaStackVis: Visually-Assisted Performance Evaluation of Metamodels in Stacking Ensemble Learning

    University essay from Linnéuniversitetet/Institutionen för datavetenskap och medieteknik (DM)

    Author : Ilya Ploshchik; [2023]
    Keywords : Visualization; interaction; metamodels; validation metrics; predicted probabilities; stacking; stacked generalization; ensemble learning; machine learning;

    Abstract : Stacking, also known as stacked generalization, is a method of ensemble learning where multiple base models are trained on the same dataset, and their predictions are used as input for one or more metamodels in an extra layer. This technique can lead to improved performance compared to single layer ensembles, but often requires a time-consuming trial-and-error process. READ MORE
