At the end of the course the student is able to: Prepare a dataset for multivariate analysis correctly; Describe multivariate data; Use multivariate statistical tests; Select appropriate distance or similarity metrics; Compute and visualize association matrices; Apply clustering algorithms and have knowledge of their principles; Apply ordination methods and have knowledge of their principles; Choose appropriate method for multidimensional data analysis based on advantages and limitations of the methods;Interpret results of multivariate analysis.
Syllabus
  • Purpose and aims of multivariate data analysis – examples of multivariate data analysis, advantages and disadvantages of multivariate data analysis, data matrices, tabular and graphical visualization of multivariate data.
  • Matrix operations, inverse matrix, characteristic polynomial, eigenvalues and eigenvectors, singular value decomposition (SVD)
  • Multivariate distributions – random variables, descriptive statistics, confidence interval, outliers
  • Multivariate statistical tests – multivariate t-test, multivariate analysis of variance
  • Distance and similarity metrics in multidimensional space
  • Association matrices – calculation and visualization, descriptive statistics, operations with association matrices (Mantel test, MEANSIM, ANOSIM, association matrix regression)
  • Hierarchical cluster analysis – agglomerative methods, divisive methods.
  • Non-hierarchical cluster analysis, identification of optimal number of clusters.
  • Ordination methods – principles of data reduction, selection and extraction of variables.
  • Ordination methods – principal component analysis (PCA)
  • Ordination methods – correspondence analysis (CA), multidimensional scaling (MDS)
  • Basics of data classification, summary of methods for multivariate data analysis.
