  1. 1. Forecasting Football Corner Odds: Statistical Modelling, Betting Strategies and Assessing Market Efficiency

    Master-uppsats, Lunds universitet/Matematisk statistik

    Författare :Gustav Pålsson; Marcus Laurens; [2023]
    Nyckelord :Mathematics and Statistics;

    Sammanfattning : Statistical modelling could be included in a betting strategy where the value of a bet is assessed by comparing model predictions and market odds. This thesis presents several models based on statistical learning methods for predicting the total number of corners in a football match. LÄS MER

  3. 2. An Empirical Comparison of Static Count Panel Data Models: the Case of Vehicle Fires in Stockholm County

    Kandidat-uppsats, Uppsala universitet/Statistiska institutionen

    Författare :Svante Pihl; Leonardo Olivetti; [2020]
    Nyckelord :Low-Mean Count Data; Poisson Regression; Negative-Binomial Regression; Panel Data Models; Vehicle Fires; Distributional Assumptions;

    Sammanfattning : In this paper we study the occurrences of outdoor vehicle fires recorded by the Swedish Civil Contingencies Agency (MSB) for the period 1998-2019, and build static panel data models to predict future occurrences of fire in Stockholm County. Through comparing the performance of different models, we look at the effect of different distributional assumptions for the dependent variable on predictive performance. LÄS MER

  4. 3. Poisson-modellering av dödsbränder i Sverige

    Kandidat-uppsats, Lunds universitet/Statistiska institutionen

    Författare :Jonatan Hedberg; Elna Lindahl; [2017]
    Nyckelord :Poisson-regression; Inhomogen Poisson-process; överspridning; dödsbränder; olycksstatistik; Inhomogenous Poisson-process; overdispersion; fatal fires; accident data; Mathematics and Statistics;

    Sammanfattning : Denna uppsats är skriven på uppdrag av Lunds tekniska högskola och Myndigheten för samhällsskydd och beredskap. Uppdraget består av att modellera antalet dödsbränder som sker i Sverige över tid, samt undersöka ifall det har skett någon signifikant förändring. LÄS MER

  5. 4. Diffusion and Productivity of an Open Source Software : CakePHP

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för industriell ekonomi

    Författare :Anwari Ilman; [2015]
    Nyckelord :diffusion of innovation; productivity; open source software;

    Sammanfattning : The purpose of this thesis was to establish an understanding on the productivity of Open Source Software (OSS) developer community through diffusion of innovation. It was empirically ascertained that network effect affects productivity of OSS community, which provide enough justification to view the matter of productivity through the lens of diffusion of innovation.

  7. 5. Flygbesiktning av Luftledningar : Modellering av samband mellan besiktningsanmärkningar och systemtillförlitlighet

    Uppsats för yrkesexamina på avancerad nivå, Tillämpad matematik och statistik

    Författare :Anna Lilly Brodersson; [2014]
    Nyckelord :regressionsanalys; Poisson GLM; negativ binomial GLM; lognormal linjär modell; driftbesiktning; luftledningar; störningsförekomster;

    Sammanfattning : This paper thoroughly investigates needs and requirements for overhead distribution feeder inspection and develops models to investigate possible relations between short term inspections remarks and outages. The study was conducted in collaboration with Fortum Distribution AB that supplied extensive information about their overhead power feeders concerning both inspection and power outages. LÄS MER
