  2. 1. Statistical modeling and design in forestry : The case of single tree models

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

    Abstract : 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. READ MORE

  4. 2. Statistical Energy Analysis and the Individual Case

    Author : Claes Fredö; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; indirect couplings; random vibration; substructuring; transmission; statistical energy analysis; energy flow; theory; three subsystem;

    Abstract : For many years, one of the most used methods for vibro-acoustic analysis of transmission of Structure-Borne Sound in complex built up structures has been the method of Statistical Energy Analysis (SEA). SEA has many advantages that makes it attractive for engineering use. READ MORE

    Keywords : NATURVETENSKAP; NATURAL SCIENCES; programming; actuarial mathematics; Statistik; cytogenetics; Genetik; cytogenetik; Mathematics; Matematik; Statistics; operations research; Genetics; ROC curves; conditioning loci; optimal score functions; noncentrality parameter; cost adjusted relative efficiency; exponential tilting; importance sampling; Monte Carlo simulation; normal approximation; crossover rate; process maximum; analytical approximation; significance calculations; NPL score; conditional linkage analysis; two-locus linkage analysis; Allele sharing; aktuariematematik; operationsanalys; programmering; gene-gene interaction; composite hypotheses; genetic disease models; classes of score functions; nonparametric linkage analysis;

    Abstract : In linkage analysis or, in a wider sense, gene mapping one searches for disease loci along a genome. This is done by observing so called marker genotypes (alleles) and phenotypes (affecteds/unaffecteds) of a pedigree set, i.e. READ MORE

  6. 4. Statistical Methods for Designed Experiments and Spectroscopic Data

    Author : Tobias Adolfsson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; saturated orthogonal designs; multiple inference; step-down testing; partial least squares; principal components regression; multiple inference;

    Abstract : This thesis consists of six papers related to saturated orthogonal designs, spectroscopic and high dimension data analysis. The first two papers deals with testing procedures for saturated orthogonal designs. Both the presented methods controls the multiple level of significance. READ MORE

  7. 5. Monoclonal gammopathy of undetermined significance : natural course and comorbidities

    Author : Ebba K Lindqvist; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Monoclonal gammopathy of undetermined significance (MGUS) is a plasma cell disorder characterized by an overproduction of monoclonal immunoglobulins. MGUS is asymptomatic but clinically relevant since annually 0.5-1.5% of individuals with MGUS will develop multiple myeloma (MM) or another malignant lymphoproliferative disease. READ MORE
