Animal Models and Integrated Nested Laplace Approximations
Holand, Anna Marie; Steinsland, Ingelin; Martino, Sara; Jensen, Henrik (Journal article; Peer reviewed, 2013)Animal models are generalized linear mixed models used in evolutionary biology and animal breeding to identify the genetic part of traits. Integrated Nested Laplace Approximation (INLA) is a methodology for making fast, ... -
The bidirectional association between depressive symptoms, assessed by the HADS, and albuminuria-A longitudinal population-based cohort study with repeated measures from the HUNT2 and HUNT3 Study
Gustad, Lise Tuset; Holand, Anna Marie; Hynnekleiv, Torfinn; Bjerkeset, Ottar; Berk, Michael; Romundstad, Solfrid (Peer reviewed; Journal article, 2022)Background Both albuminuria and depression are associated with cardiovascular disease, reflecting low-grade systemic inflammation and endothelial dysfunction. They share risk factors including weight, blood pressure, ... -
Genetic variation and structure of house sparrow populations: is there an island effect?
Jensen, Henrik; Moe, Rune; Hagen, Ingerid Julie; Holand, Anna Marie; Kekkonen, Jaana; Tufto, Jarle; Sæther, Bernt-Erik (Journal article; Peer reviewed, 2013)Population genetic structure and intrapopulation levels of genetic variation have important implications for population dynamics and evolutionary processes. Habitat fragmentation is one of the major threats to biodiversity. ... -
Is my study system good enough? A case study for identifying maternal effects
Holand, Anna Marie; Steinsland, Ingelin (Journal article; Peer reviewed, 2016)In this paper, we demonstrate how simulation studies can be used to answer questions about identifiability and consequences of omitting effects from a model. The methodology is presented through a case study where ... -
On estimation and identifiability issues of sex-linked inheritance with a case study of pigmentation in Swiss barn owl (Tyto alba)
Larsen, Camilla Thorrud; Holand, Anna Marie; Jensen, Henrik; Steinsland, Ingelin; Roulin, Alexandre (Journal article; Peer reviewed, 2014)Genetic evaluation using animal models or pedigree-based models generally assume only autosomal inheritance. Bayesian animal models provide a flexible framework for genetic evaluation, and we show how the model readily can ... -
Statistical methods for estimating intra- and inter-population variation in genetic diversity
Holand, Anna Marie (Doktoravhandlinger ved NTNU, 1503-8181; 2013:239, Doctoral thesis, 2013)Knowledge of the level of (additive) genetic variation within and among populations is important for our understanding of the future direction and rate of evolutionary change. In this thesis I first investigate how ...
