  1. 1. Point process learning for non-parametric intensity estimation with focus on Voronoi estimation

    Master-uppsats, Göteborgs universitet/Institutionen för matematiska vetenskaper

    Författare :Alexander Thorén; [2023-03-28]
    Nyckelord :;

    Sammanfattning : Point process learning is a new statistical theory that gives us a way to estimate parameters using cross-validation for point processes. By thinning a point pattern we are able to create training and validation sets which are then used in prediction errors. LÄS MER

  3. 2. Failure Probability and Lifetime Estimation for Industrial Robots : A Logistic Regression and Lifetime Analysis Approach

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för matematik och matematisk statistik

    Författare :Erik Fahlbeck Carlsson; Martin Herbert; [2023]
    Nyckelord :Lifetime Analysis; Logistic regression; Prediction; Lifetime estimation; Industrial robots; Livslängdsanalys; Logistisk regression; Prediktion; Livslängdsestimering; Industriella robotar;

    Sammanfattning : The ability to handle and process data for information extraction is getting more and more important. Using extracted data from the business to improve productivity is seen as an important part in developing the business processes. In this thesis, industrial robots and their survival times are analyzed. LÄS MER

  4. 3. Robust Non-Linear State Estimation for Underwater Acoustic Localization : Expanding on Gaussian Mixture Methods

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Diogo Antunes; [2023]
    Nyckelord :Robust state estimation; Underwater localization; Target tracking; Gaussian mixture; AUV; Estimação robusta de estado; Localização subaquática; Rastreamento de alvos; Mistura Gaussiana; AUV; Robust tillståndsuppskattning; Undervattenslokalisering; Målspårning; Gaussisk blandning; AUV;

    Sammanfattning : Robust state estimation solutions must deal with faulty measurements, called outliers, and unknown data associations, which lead to multiple feasible hypotheses. Take, for instance, the scenario of tracking two indistinguishable targets based on position measurements, where each measurement could refer to either of the targets or even be a faulty reading.

  5. 4. Forecasting Value-at-Risk and Expected Shortfall: A comparison of non- and parametric methods for crude oil amidst extreme volatility

    Magister-uppsats, Lunds universitet/Nationalekonomiska institutionen

    Författare :Otto Colbin; Yugam Sharma; [2023]
    Nyckelord :Value-at-Risk VaR ; Expected Shortfall ES ; Nonparametric estimation methods; Parametric estimation methods; Crude oil.; Business and Economics;

    Sammanfattning : Practitioners primarily utilise nonparametric methods when estimating Value-at- Risk (VaR) and Expected Shortfall (ES) for computing capital requirements. However, various researchers assert that there are issues with those estimates, particularly amidst periods of market turmoil. LÄS MER

  7. 5. Assessing the Eco-efficiency of Swedish Crop Farms and the Role of Subsidies : a Directional Distance Function Approach

    Master-uppsats, SLU/Dept. of Economics

    Författare :Therese Ratilla; [2023]
    Nyckelord :Swedish crop farmers; CAP subsidies; FADN; stochastic frontier analysis; multi-output; one-step approach;

    Sammanfattning : The agriculture sector’s contribution to global greenhouse gas (GHG) emissions and its increasing vulnerability to the effects of climate change warrants assessments considering not only on-farm productivity but also the industry’s environmental sustainability. Utilizing the concept of eco-efficiency, this study analyzes the environmental performance of Swedish crop farms by incorporating farm-level GHG emissions as an undesirable output in the production function.
