Course objectives

In this course you can learn main statistical methods (mainly those multidimensional) needed by you biosystematical, taxonomical and phylogenetical research. The main objective is learn you (without redundant mathematics) to understand and to actively use these methods by designing of your experiments, analyses, and sampling. You will train each method yourself in practicals following the theoretical lectures. You should learn how to correctly and effectively form hypotheses, ask research questions; how many, why, from where, and which one samples to collect; how many times and what to measure. You will learn to inspect multidimensional data by ordination diagrams (PCA, PCoA, CVA, NMDS), to test mutually various multidimensional data sets (Mantel test, Procrustes analysis), to construct and to test classifications of your samples, and to find out the most proper identification characters, e.g. useful for identification keys (discriminant analysis). You will get knowledge how to build phenetic and evolutionary trees from morphological and molecular/sequence data (UPGMA, NJ trees, LS trees, minimum evolution trees, maximum parsimony), how to understand and interpret trees.You will learn how to test the phylogenetic dependence of characters, how to correctly calculate correlation and regression with phylogenetically dependent data, and how to model the evolution of characters on trees.

Learning outcomes

After completing the course the student will be able to:
- Plan an effective data collection design
- Analyse own data using appropriate statistical methods (classical linear, multidimensional, phylogenetic)
– Construct phylogenetic (evolution) trees based on DNA sequence or morphological data
- Properly interpret the results of individual analyzes and discuss their possible weaknesses
