(Peer reviewed; Journal article, 2014)Orthogonal projections to latent structures (OPLS) and target projection (TP) are two alternative methods for separation of predicting and non-predicting parts of the predictor matrix in partial least squares regression ... -
Microevolutionary system identification and climate response predictions by use of BLUP prediction error method
(Peer reviewed; Journal article, 2023)Animals and other organisms in wild populations may adjust to climate change by means of plasticity and evolution, and it is an important task to find the contributions from each of these effects. Attempts to solve this ... -
A BLUP derivation of the multivariate breeder’s equation, with an elucidation of errors in BLUP variance estimates, and a prediction method for inbred populations
(Peer reviewed; Journal article, 2022)The multivariate breeder's equation, Lande (1979), was derived from the Price equation Price (1970,1972). Here, I present a derivation based on the BLUP (best linear unbiased predictions) equations in matrix form, first ... -
Microevolutionary system identification and climate response predictions
(Peer reviewed; Journal article, 2022)Microevolutionary system identification was introduced Ergon (2022), with the specific purpose to show that predictions of genetic adaptations to climate change require that environmental reference values are properly ... -
Dynamical BLUP modeling of reaction norm evolution, accommodating changing environments, overlapping generations, and multivariate data
(Peer reviewed; Journal article, 2023)For theoretical studies, reaction norm evolution in a changing environment can be modeled by means of the multivariate breeder's equation, with the reaction norm parameters treated as traits in their own right. This is, ... -
Pedagogical Perspectives of Interdisciplinary Teaching and Research: An Energy System Modelling Outlook in Relation to Energy Informatics

Detecting emergence in engineered systems: A literature review and synthesis approach
(Peer reviewed; Journal article, 2023)Modern product development often generates systems of high complexity that are prone to emergent behavior. The industry has a need to establish better practices to detect inherent emergent behavior when engineering such ... -
The important choice of reference environment in microevolutionary climate response predictions
(Peer reviewed; Journal article, 2022)It is well documented that individuals of wild populations can adjust to climate change by means of phenotypic plasticity, but few reports on adaptation by means of genetically based microevolution caused by selection. ... -
