  3. 2. 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

  4. 3. A Study Of Using Communication Signals As Sonar Pulses In Underwater Sensor Systems

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Signaler och system

    Författare :Erica Svensson; [2022]
    Nyckelord :Sonar; Communication signal; Beamforming; Underwater sensor system; WLS estimator; Detection algorithm; Position estimation;

    Sammanfattning : Underwater communication within underwater sensor network is crucial for surveillance of coast and ocean areas. The aim of this report was to examine whether it is realistic to use the communication signal which is sent from one node to another as a sonar pulse, and in such case at what distances. LÄS MER

  5. 4. Dimensionality Reduction in High-Dimensional Profile Analysis Using Scores

    Master-uppsats, Linköpings universitet/Tillämpad matematik; Linköpings universitet/Tekniska fakulteten

    Författare :Jonathan Vikbladh; [2022]
    Nyckelord :High-dimensional data; Hypothesis testing; LR test; Linear scores; Multivariate analysis; Profile analysis; Spherical distributions;

    Sammanfattning : Profile analysis is a multivariate statistical method for comparing the mean vectors for different groups. It consists of three tests, they are the tests for parallelism, level and flatness. The results from each test give information about the behaviour of the groups and the variables in the groups.

  7. 5. Constructing and commissioning of a Multi-Grid neutron detector prototype for the European Spallation Source

    Master-uppsats, Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen; Lunds universitet/European Spallation Source ESS AB

    Författare :Rebecka Wahlén; [2022]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : A prototype of a novel 10B-based neutron detector called the Multi-Grid detector has been constructed, tested and commissioned for the European Spallation Source (ESS). The detector is constructed after the specifications set by the CSPEC instrument at ESS and is therefore called the CSPEC Multi-Grid detector. LÄS MER
