    Keywords : foundation-owned business; family business; ownership; innovation; collaboration strategiess;

    Abstract : Background: Ongoing business transformations, labour shortages, and lack of resources are perceived as some of the business’s biggest challenges. Since innovation is a key driver for growth and profitability, it is indispensable for the long-term survival of a business. READ MORE

  4. 3. Predictive Modeling and Statistical Inference for CTA returns : A Hidden Markov Approach with Sparse Logistic Regression

    University essay from Umeå universitet/Institutionen för matematik och matematisk statistik

    Author : Oskar Fransson; [2023]
    Keywords : Probability theory; Statistical inference; finance; CTA; managed futures; machine learning; statistical learning; stochastic process; sparse logistic regression; Markov Chain Monte Carlo; Hidden Markov model;

    Abstract : This thesis focuses on predicting trends in Commodity Trading Advisors (CTAs), also known as trend-following hedge funds. The paper applies a Hidden Markov Model (HMM) for classifying trends. Additionally, by incorporating additional features, a regularized logistic regression model is used to enhance prediction capability. READ MORE

  5. 4. Ray-Tracing Modeling of Grating Lobe Level Reduction by Using a Dielectric Dome Antenna

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)
