    Abstract : In everyday life, the ability to perform two tasks simultaneously, dual task, is an omnipresent issue. There are several factors that can limit an individual’s ability to dual task, such as neurological pathologies, or physical disabilities. READ MORE

  3. 3. Capturing Tail Risk in a Risk Budgeting Model

    University essay from KTH/Matematisk statistik; KTH/Matematisk statistik

    Author : Filip Lundin; Markus Wahlgren; [2020]
    Keywords : ;

    Abstract : Risk budgeting, in contrast to conventional portfolio management strategies, is all about distributing the risk between holdings in a portfolio. The risk in risk budgeting is traditionally measured in terms of volatility and a Gaussian distribution is commonly utilized for modeling return data. READ MORE

  5. 5. Modeling asymmetry in volatility response - non-Gaussian innovations approach

    University essay from Lunds universitet/Statistiska institutionen

    Author : Ludvig Göransson; [2020]
    Keywords : ARCH; GARCH; APARCH; Asymmetric GARCH; non-Gaussian innovations; Laplace distribution; Leverage effect; Stylized facts; Volatility process.; Mathematics and Statistics;

    Abstract : This thesis is an explorative note on the non-Gaussian innovations of the volatility process. More specifically, the thesis investigates if the decomposition of the Standard Classical Laplace (SCL) distribution to a difference of two exponential is a valid alternative to modelling the asymmetric volatility processes, taking volatility clustering, the leverage effect and asymmetric response in volatility into account.
