    Sammanfattning : In this thesis several stochastic volatility models are presented and used to estimate the risk of a collection of Swedish stocks, as well as of a portfolio consisting of said stocks. Model parameters are estimated using the PSAEM algorithm. LÄS MER

  2. 2. Classification of HRV-signals using Time-Frequency Analysis

    Kandidat-uppsats, Lunds universitet/Matematisk statistik

    Författare :Ante Forsgren; Henrik Kragh; [2018]
    Nyckelord :Mathematics and Statistics;

    Sammanfattning : Heart rate variability (HRV) is a term within cardiology describing the natu- rally occurring variation of the time interval between heartbeats, and high HRV activity has been linked to both cardiovascular and non-cardiovascular health. This bachelor thesis aims to find differences between HRV-signals where short term physical strain (pain) was induced and HRV-signals where no such strain was applied. LÄS MER
