  2. 2. Multivariate Aspects of Phylogenetic Comparative Methods

    Detta är en avhandling från Göteborg : University of Gothenburg

    Författare :Krzysztof Bartoszek; Göteborgs universitet.; Gothenburg University.; [2011]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; General Linear Model; Ornstein-Uhlenbeck process; Multivariate phylogenetic comparative method; Evolutionary model; Adaptation; Optimality; Measurement error; Regression; Adaptation; Major-axis regression; Reduced major-axis regression; Structural equation; Allometry; Phylogenetic inertia;

    Sammanfattning : his thesis concerns multivariate phylogenetic comparative methods. We investigate two aspects of them. The first is the bias caused by measurement error in regression studies of comparative data. We calculate the formula for the bias and show how to correct for it. LÄS MER

  3. 3. Rank Estimation in Elliptical Models Estimation of Structured Rank Covariance Matrices and Asymptotics for Heteroscedastic Linear Regression

    Detta är en avhandling från Uppsala : Universitetsbiblioteket

    Författare :Kristi Kuljus; Uppsala universitet.; [2008]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; elliptical distributions; multivariate ranks; rank covariance matrix; linear rank regression; heteroscedastic errors; linear rank statistics; MATHEMATICS Applied mathematics Mathematical statistics; MATEMATIK Tillämpad matematik Matematisk statistik;

    Sammanfattning : This thesis deals with univariate and multivariate rank methods in making statistical inference. It is assumed that the underlying distributions belong to the class of elliptical distributions. LÄS MER

  4. 4. Optimal Segmentation of Linear Regression Parameters

    Detta är en avhandling från Linköping University

    Författare :Fredrik Gustafsson; Linköpings universitet.; Linköpings universitet.; [1990]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The problem of detecting multiple changes in the dynamical properties of a measured signal, which we call segmentation, is studied. A Bayesian model-based approach is used. The signal is supposed to be described by a linear regression. The posterior distribution for the change instants is first derived for a quite general signal model. LÄS MER

  5. 5. A regression approach for assessment of building energy performance

    Detta är en avhandling från Umeå : Umeå universitet

    Författare :Jimmy Vesterberg; Umeå universitet.; [2014]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; building energy simulation; measurements; regression; calibration parameters;

    Sammanfattning : Reliable evaluation methods is needed to ensure that investments in energy conservation measures (ECMs) and the construction of new energy efficient buildings lives up to the promised and expected performance.This thesis presents and evaluates a regression method for estimation of influential building parameters: transmission losses above ground (including air leakage), ground heat loss, and overall heat loss coefficient.
