  3. 27. Essays on Financial Market Volatility

    Författare :Ai Jun HOU; Nationalekonomiska institutionen; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Nonparametric GARCH model; News Impact Curve; Interest rate volatility; MCMC; Markov Switching; Chinese stock markets; EMU stock markets;

    Sammanfattning : This thesis examines the volatility in the equity and short-term interest-rate markets, and the spillover from the short term interest rate market to the equity market. It consists of three papers and focuses on adapting and proposing models for the estimation and forecasting of financial market volatility. LÄS MER

  4. 28. On Power Estimation and Score Predictions in Affected Sib-Pair Linkage Analysis

    Författare :Mikael Knutsson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; affected sib-pair; linkage analysis; nonparametric linkage score; sib prevalence; statistical genetics; nonparametric linkage score;

    Sammanfattning : This thesis consists of three papers in statistical genetics, with the emphasis on affected sib-pair linkage analysis. In Paper A, a method to derive the power of linkage analysis in genome scans, using a stepwise approach, is presented. LÄS MER

  5. 29. Position Estimation and Tracking in Colloidal Particle Microscopy

    Författare :Mats Kvarnström; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; censored regression; colloidal chemistry; depth estimation; diffusion coefficient; nonparametric function estimation; position estimation; rotational symmetry; tracking; template matching; video microscopy; rotational symmetry;

    Sammanfattning : This thesis presents methods for estimating the locations (including depth) of spherical colloidal particles in images recorded in video microscopy. Understanding the behavior of colloidal interactions and diffusion is of crucial importance in a vast number of areas. LÄS MER
