  1. 16. Favourable Opportunities in Sports Betting - A Statistical Approach to Football Goals in the Premier League

    Kandidat-uppsats, KTH/Matematisk statistik

    Författare :Fredrik Lindau; Gustaf Carle; [2022]
    Nyckelord :statistics; Poisson distribution; Negative Binomial distribution; Bayesian regression; football; Premier League; sports betting; market efficiency; probability theory; estimations; statistik; Poisson fördelning; Negativ Binomial fördelning; Bayesiansk regression; fotboll; Premier League; betting; marknadseffektivitet; sannolikhetsteori; skattningar;

    Sammanfattning : The premise of this report is to delve into sports betting and whether favourable opportunities can be found, more specifically focusing on over and under odds for number of goals scored in football games of the Premier League. Using historical data from football matches several models are developed, the characteristics of goals warranting the use of probability based Poisson and Negative Binomial models, as well as Bayesian Poisson regression for goal predictions.

  3. 17. Evaluation of Probabilistic Programming Frameworks

    Master-uppsats, Uppsala universitet/Statistiska institutionen

    Författare :Carl Munkby; [2022]
    Nyckelord :Computational statistics; Bayesian statistics; Probabilistic programming; Probabilistic modelling; Stan; TensorFlow Probability; Pyro; NumPyro; Markov Chain Monte Carlo; Hamiltonian Monte Carlo; NUTS;

    Sammanfattning : In recent years significant progress has been made in the area of Probabilistic Programming, contributing to a considerably easier workflow for quantitative research in many fields. However, as new Probabilistic Programming Frameworks (PPFs) are continuously being created and developed, there is a need for finding ways of evaluating and benchmarking these frameworks. LÄS MER

  4. 18. Rätt sida femprocentsspärren

    Kandidat-uppsats, Lunds universitet/Statistiska institutionen

    Författare :Mårten Augustsson; Ida Haggren; [2022]
    Nyckelord :Opinion polls; sampling theory; bayesian statistics; multinomial distribution; dirichlet distribution.; Mathematics and Statistics;

    Sammanfattning : This bachelor’s thesis in statistics explores frequentist and bayesian methods for parameter estimation and compares their usefulness when applied to opinion polls of party sympathies in the Swedish political system. Through simulation in R, random samples are generated from a population modelled after the Swedish electorate at various points during the 2010s and 2020s. LÄS MER

  5. 19. How Hunters’ Harvest Rate Varies in Response to Population Densities of Fallow Deer (Dama dama), Roe Deer (Capreolus capreolus), and Wild Boar (Sus scrofa)

    Master-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologi

    Författare :Felicia Skorsdal; [2022]
    Nyckelord :Bayesian statistics; Capreolus capreolus; Dama dama; Hunters’ harvest rate; Ungulate management; Spatiotemporal analysis; Sus scrofa;

    Sammanfattning : For many species, population size data is difficult to obtain or even unavailable. Therefore, estimations or indirect abundance measures of populations are crucial for ungulate management. Hunting has an important role in wildlife management, and is a partnership between state, landowners, and hunting communities. LÄS MER

  7. 20. Assessment of Modern Statistical Modelling Methods for the Association of High-Energy Neutrinos to Astrophysical Sources

    Master-uppsats, KTH/Matematisk statistik

    Författare :Valentin Minoz; [2021]
    Nyckelord :Statistics; Astrophysics; Neutrino sources; Mixture models; Monte Carlo methods; Maximum likelihood estimation; Statistik; Astrofysik; Neutrinokällor; Blandningsmodeller; Monte Carlo-metoder; Maximum likelihood-metoden;

    Sammanfattning : The search for the sources of astrophysical neutrinos is a central open question in particle astrophysics. Thanks to substantial experimental efforts, we now have large-scale neutrino detectors in the oceans and polar ice. LÄS MER
