Concurrent ordination: Simultaneous unconstrained and constrained latent variable modelling
van der Veen, Bert; Hui, Francis K. C.; Hovstad, Knut Anders; OHara, Robert Brian (Peer reviewed; Journal article, 2022)1. In community ecology, unconstrained ordination can be used to indirectly explore drivers of community composition, while constrained ordination can be used to directly relate predictors to an ecological community. ... -
Model-based ordination for species with unequal niche widths
van der Veen, Bert; Hui, Francis K. C.; Hovstad, Knut Anders; Solbu, Erik Blystad; OHara, Robert Brian (Peer reviewed; Journal article, 2021)1. It is common practice for ecologists to examine species niches in the study of community composition. The response curve of a species in the fundamental niche is usually assumed to be quadratic. The centre of a quadratic ... -
Modelling temperature-driven changes in species associations across freshwater communities
Perrin, Sam; van der Veen, Bert; Golding, Nick; Finstad, Anders Gravbrøt (Peer reviewed; Journal article, 2021)Due to global climate change–induced shifts in species distributions, estimating changes in community composition through the use of Species Distribution Models has become a key management tool. Being able to determine how ... -
Rotations in Factor Analysis
Singdahlsen, Martinius Theodor (Bachelor thesis, 2022)Denne oppgaven vil omhandle faktoranalyse med hovedfokus på faktormodellens rotasjoner. Rotasjoner brukes både for å kunne trekke slutninger og for å bedre tolke dataene. I denne sammenheng vil vi se på kriteriene som er ... -
