Prerequisites (in Czech)
Bi5040 Biostatistics - basic course
Výklad navazuje na znalosti získané v předmětu Bi5040 Biostatistika, zejména na regresní analýzu a obecné lineární modely, a bylo by proto lepší, aby si studenti tento předmět zapsali až po absolvování Biostatistiky. Pokud chce student i přesto tento předmět navštěvovat (např. aby se naučil analytické metody nutné pro zpracování bakalářské práce), může na přednášky chodit s tím, že se individuálně domluvíme na způsobu ukončení předmětu (např. zkoušku uděláme až po zkoušce z Biostatistiky nebo v dalším školním roce). Užitečné, nikoliv však nezbytné, je také předchozí absolvování předmětu Bi6549 Zpracování základních botanických dat.

Course objectives
The course deals with basic methods of statistical analysis of the data on species composition of plant and animal communities, irrespective of their taxonomical delimitation. The focus is on numerical classification and ordination methods and analysis of the relationships between species composition and environmental factors.
At the end of this course, students should be able to apply particular methods, using standard software packages such as PC-ORD, CANOCO and Statistica. And becouse I believe that the future of data analysis is in R program, each lecture will have a short "five minutes with R" part - short demonstration of particular statistical methods in the environment of R program (however, knowledge of R and it's active use will not be either required or expected).

Teaching methods
frontal lecture, which combines theory with demonstration of statistical software
Assessment methods
For exam, students will prepare a short study, in which they analyze their own or demonstration data, using the statistical approaches discussed in the lecture. The study should have a form of short scientific paper. The exam is oral discussion about the study, with additional broadening questions, which should prove that student haven't slept during the lecture.
