  1. 11. A regression approach for assessment of building energy performance

    Författare :Jimmy Vesterberg; Thomas Olofsson; Mohsen Soleimani-Mohseni; Björn Reidar Sörensen; Sofia Lidelöw; Umeå universitet; []
    Nyckelord :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.

  4. 13. Statistical modeling and design in forestry : The case of single tree models

    Författare :Leakemariam Berhe; Göran Arnoldsson; Göran Broström; Dieter Rasch; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Forest data; Covariance structures; Nonlinear mixed effects models; Tree taper models; Ds-optimal design; Replication-free design.; Statistics; Statistik;

    Sammanfattning : Forest quantification methods have evolved from a simple graphical approach to complex regression models with stochastic structural components. Currently, mixed effects models methodology is receiving attention in the forestry literature. LÄS MER

  5. 14. Estimators of semiparametric truncated and censored regression models

    Författare :Maria Karlsson; Thomas Laitila; Göran Broström; Kenneth Carling; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Statistics; LTRC; consistency; asymtotic normality; bootstrap; interpurchase intervals; Statistik; Statistics; Statistik; Statistics; statistik;

    Sammanfattning : This thesis contributes in several ways to the existing knowledge on estimation of truncated, censored, and left truncated right censored (LTRC) regression models. Three new semiparametric estimators are proposed, allowing for asymmetric error distributions. LÄS MER
