Multivariate analysis of biological data using R


ECTS credits: 1.5 ECTS


Course parameters:

Language: English

Level of course: PhD Course

Time of year: Autumn 2024 (6 – 8 August 2024)

Capacity limits: 30

Course fee: DKK 350


Objectives of the course:

The course aims to introduce the analysis of multivariate data arising from observation and experimental studies with the R statistical software.


Learning outcomes and competences:
At the end of the course, the student should be able to:

  • have a good introductory understanding of the main ordination approaches used in the analysis of multivariate data sets
  • be able to choose an appropriate method to use to analyse a data set
  • understand how to use restricted permutation tests with constrained ordination methods to test the effects of predictor variables or experimental treatments
  • be able to use the R statistical software to analyse multivariate data


Compulsory programme:

Active participation in the course including attendance at lectures and completion of computer-based classes and exercises. Completion of short, computer-based assessments testing their understanding of a topic and the practical skills taught. For credit, students must complete a data analysis exercise to be submitted one week after the end of the course (16th August).


Course contents:

The course is based on a series of lectures and computer based practical classes led by an international expert in the analysis of multivariate data, who is also one of the senior developers of the vegan R package and the creator of the permute R package.

The course covers the following topics:

  • An introduction to multivariate data and their analysis
  • Dissimilarity and dissimilarity coefficients
  • Unconstrained ordination
    • Principal Components Analysis
    • Correspondence Analysis
    • Principal Coordinates Analysis
    • Non-metric Multidimensional Scaling
  • Constrained ordination
    • Redundancy Analysis
    • Canonical Correspondence Analysis
    • Distance-based Redundancy Analysis
    • PERMANOVA and PERMDISP
  • Statistical testing using permutation tests


Prerequisites:

This course is suitable for Phd students (including senior thesis-based MSc students) and researchers working with multivariate data sets in biology (inter alia animal science, ecology, agriculture, microbial ecology/microbiology). Some prior knowledge of R is required.
