Contributions to the multivariate Analysis of Marine Environmental Monitoring

Autor: Graffelman, Jan

Publikováno v: TDX (Tesis Doctorals en Xarxa).

The thesis parts from the view that statistics starts with data, and starts by introducing the data sets studied: marine benthic species counts and chemical measurements made at a set of sites in the Norwegian Ekofisk oil field, with replicates and a
