  1. 1. Robustness Against Non-Normality : Evaluating LDA and QDA in Simulated Settings Using Multivariate Non-Normal Distributions

    Kandidat-uppsats, Uppsala universitet/Statistiska institutionen

    Författare :Gånheim Viktor; Åslund Isak; [2023]
    Nyckelord :Classification; Linear Discriminant Analysis; Quadratic Discriminant Analysis; Normality Assumption;

    Sammanfattning : Evaluating classifiers in controlled settings is essential for empirical applications, as extensive knowledge on model-behaviour is needed for accurate predictions. This thesis investigates robustness against non-normality of two prominent classifiers, LDA and QDA. LÄS MER

  3. 2. Maskininlärning & Random Forest: Överträffar traditionella kreditmodeller

    Kandidat-uppsats, Lunds universitet/Nationalekonomiska institutionen

    Författare :Simon Johansson; [2023]
    Nyckelord :Altman Z-Score; Random Forest; Machine Learning; Bankruptcy prediction; Business and Economics;

    Sammanfattning : The Altman Z-Score model is one of the most famous models för predicting bankruptcy and measuring financial distress for companies. It uses multivariate discriminant analysis to classify companies in three different groups based on their calculated Z-Score. LÄS MER

  4. 3. Z-Altman's model effectiveness in bank failure prediction-The case of European banks

    Magister-uppsats, Lunds universitet/Nationalekonomiska institutionen

    Författare :Charalampos-Orestis Manousaridis; [2017]
    Nyckelord :European banks; financial health; prediction models; multivariate discriminant analysis; Z-score model; Altman; Business and Economics;

    Sammanfattning : The corporate bankruptcy is a significant problem for economy since it is considered as a limiting factor for economic growth. The financial crisis that broke out in USA on 2007 as a result of miscalculated subprime mortgage strategies turn into a full international banking crisis affecting successively the European banks, especially those of South European countries.

  5. 4. "Source characterization of soils contaminated with Polycyclic Aromatic Compounds (PACs) by use of Partial Least Squares Discriminant Analysis (PLS-DA)"

    Magister-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknik

    Författare :Tim Sinioja; [2017]
    Nyckelord :;

    Sammanfattning : Polycyclic aromatic compounds (PACs) are organic compounds that include several sub-groups of toxic, persistent and carcinogenic environmental pollutants consisting of two or more non-substituted or substituted aromatic rings. Due to the complexity of PAC-mixtures found in the environment it can be challenging and time-consuming to track the sources of contamination. LÄS MER

  7. 5. Potential för utökad areal sådd inom Holmen Skog

    Uppsats för yrkesexamina på avancerad nivå, SLU/Department of Forest Biomaterials and Technology (from 131204)

    Författare :Patrik Lundström; [2015]
    Nyckelord :ståndort; multivariatanalys; PCA; PLS-DA; tall; contorta;

    Sammanfattning : Holmen Skog har som målsättning att öka andelen sådda föryngringsytor från dagens 24 % till 30 %. Erfarenheterna inom Holmen Skog vad gäller sådd är goda, men med ett ökat arealmål blir svårigheterna att hitta lämpliga bestånd större. LÄS MER
