  1. 1. Simulation-Based Portfolio Optimization with Coherent Distortion Risk Measures

    Master-uppsats, KTH/Matematisk statistik

    Författare :Andreas Prastorfer; [2020]
    Nyckelord :Risk Management; Portfolio Optimization; Conditional Value-at-Risk; Coherent Distortion Riks Measures; Elliptical Distribution; GARCH model; Normal Copulas; Extreme Value Theory; Risk Contributions; Riskhantering; Portföljoptimering; Conditional Value-at-Risk; Koherenta distortionsriskmått; Elliptiska fördelningar; GARCH modeller; Normal-copula; Extremvärdes teori; Riskbidrag;

    Sammanfattning : This master's thesis studies portfolio optimization using linear programming algorithms. The contribution of this thesis is an extension of the convex framework for portfolio optimization with Conditional Value-at-Risk, introduced by Rockafeller and Uryasev. LÄS MER

  2. 2. The Impact of Weather on Residential Fires in Sweden: A Regression Analysis

    Kandidat-uppsats, KTH/Matematisk statistik; KTH/Matematisk statistik

    Författare :Viktor Reineck; Folke Ulfsparre; [2019]
    Nyckelord :Regression; Poisson; Negative binomial; Generalized linear models; Organizational theory; Regression; Poisson; Negativ binomial; Generaliserade linjära modeller; Organisationsteori;

    Sammanfattning : The purpose of this report is to investigate possible relationships between the number of residential fires in Sweden and various weather parameters. The study is conducted based on a hypothesis as stated by the MSB, the Swedish Civil Contingencies Agency, that behavioral factors related to weather can have an influence on the number of residential fires.

  3. 3. Fire effects in a landscape of fear : food availability and perceived predation risk as potential determinants of patch utilization by herbivore prey

    Master-uppsats, SLU/Dept. of Wildlife, Fish and Environmental Studies

    Författare :David Kymmell; [2019]
    Nyckelord :landscape of fear; forest fire effects; herbivore prey; camera trapping;

    Sammanfattning : Context: A major effect of climatic change is the global increase in forest fires, which potentially creates an increase in food availability for herbivorous species. Also vegetation density and the numbers of tree logs increase in burned sites, and this is thought to influence the perceived risk of herbivore prey species, which affects their anti‐predator behaviour and thereby the patch utilization.

  4. 4. Modelling growth of Norway spruce on former agricultural lands in Latvia

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Andis Zvirgzdiņš; [2019]
    Nyckelord :Norway spruce plantations; young stands; height development; generalized algebraic difference approach; growth simulations;

    Sammanfattning : Adequate growth forecasts are essential for forest management planning. In order to make such forecasts, accurate growth models are required. Due to the rapid growth of Norway spruce (L.) Karst. LÄS MER

  5. 5. Browsing behaviour in complex ungulate multi-species systems in Southern Sweden

    Master-uppsats, SLU/Dept. of Wildlife, Fish and Environmental Studies

    Författare :Jonatan Sandberg; [2019]
    Nyckelord :browsing pressure; interspecific competition; multi-species;

    Sammanfattning : In recent years several of the ungulate species present in Sweden have increased in both densities and distribution. Browsing pressure has mainly been attributed to moose but recent research shows that with more complex ungulate ecosystems new interactions and connections might emerge. LÄS MER
