Multivariate Analysis

to be announced

Scope

The multidimensional data on community composition, properties of individual populations, or properties of environment are the bread and butter of an ecologist’s life. They need to be analysed with taking their multidimensionality into account. A reductionist approach of looking at the properties of each variable separately does not work in most cases. The methods for statistical analysis of such data sets fit under the umbrella of ‘multivariate statistical methods’. In this course, our intention is to provide the participant with both the basic understanding of principles of multivariate methods and the skills needed to use those methods in his/her own work.

Programme
  • Day 1: Collecting data, multiple linear regression and polynomials, selection of variables, comparing models and GenStat for Windows.
  • Day 2: Loglinear models, analysis of presence-absence data, logistic regression analyses with the Gaussian response model and an introduction to multivariate analysis.
  • Day 3: Ordination, Direct and indirect analysis of gradients, Length of gradient, Principal components analysis (PCA), Redundancy analysis (RDA), Interpretation biplots of PCA and RDA, Canoco for Windows (4.5).
  • Day 4: Ordination based on Correspondence analysis methods (CA, CCA and DCA) Interpretation CA/DCA plots, Choice of method.
  • Day 5: Cluster analysis, choice of similarity measure, agglomerative methods, divisive methods, TWINSPAN, model-based approaches and interpretation.
