  3. 17. Bayesian Networks for Modelling the Respiratory System and Predicting Hospitalizations

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

    Författare :Victor Lopo Martinez; [2023]
    Nyckelord :Bayesian Networks; Structure Learning; Conditional Probability Tables; Maximum Likelihood Estimator; XGBoost; and Respiratory System; Bayesianska nätverk; Strukturinlärning; Villkorliga sannolikhetstabeller; Maximum Likelihood Estimator; XGBoost; och Andningssystemet;

    Sammanfattning : Bayesian networks can be used to model the respiratory system. Their structure indicate how risk factors, symptoms, and diseases are related and the Conditional Probability Tables enable predictions about a patient’s need for hospitalization. LÄS MER

  4. 18. Public Domain Intelligence Tests: Psychometric properties of the Cog15 and ICAR16 cognitive ability scales

    Master-uppsats, Lunds universitet/Institutionen för psykologi

    Författare :Dagný Kristjánsdóttir; Aya Zaiter; [2023]
    Nyckelord :general intelligence; intelligence testing; public domain; CFA; PCA; Social Sciences;

    Sammanfattning : The current paper aims to explore the psychometric properties of two public domain cognitive ability scales, Cog15 and ICAR16, and investigate how well they each capture the g-factor in a Swedish sample (N = 428). The motivation for choosing these aims is that public domain, free, and easily accessible intelligence tests are needed for measuring the g-factor. LÄS MER

  5. 19. Credit scoring using Logistic regression

    Master-uppsats, Mälardalens universitet/Akademin för utbildning, kultur och kommunikation

    Författare :Iftho Hara Khanam; [2023]
    Nyckelord :Kurtosis; Skewness; Winsorization; Logistic regression analysis; Maximum likelihood estimation; Newton–Raphson method; T–ratio test; P-value; LR test;

    Sammanfattning : In this thesis, we present the use of logistic regression method to develop a credit scoring modelusing the raw data of 4447 customers of a bank. The data of customers is collected under 14independent explanatory variables and 1 default indicator. The objective of this thesis is toidentify optimal coefficients. LÄS MER

  7. 20. Forecasting Technological Diffusion through Analogies: Examining Historical Technologies to Assess the Future Growth of Green Hydrogen Electrolysis and Pipeline Network as Climate Mitigation Technologies

    Master-uppsats, Lunds universitet/Internationella miljöinstitutet

    Författare :Renz Homer Cerillo; [2023]
    Nyckelord :Technology diffusion; green hydrogen; electrolyze; pipeline; feasibility spaces; reference case forecasting; Earth and Environmental Sciences;

    Sammanfattning : Green hydrogen is an advantageous clean energy carrier that enables the decarbonization of hard-to-abate sectors and addresses the intermittency of renewables. However, its global production is currently constrained by inadequate infrastructure, high investment risks, and relatively technological infancy. LÄS MER
