The course will primarily use students own data. In the beginning of the course each student should give an oral presentation of the background for their data, problems/hypothesis to be addressed. By intellectual teamwork/discussions and skilled supervising, good graphical presentations will be suggested, followed by relevant statistical analysis. Relevant statistical methods will be presented shortly in theory and practise. A short presentation of multivariate methods will be given, but a detailed and more developed introduction will be given in the PhD-course Bio-8514. The main platform for graphical presentation and statistical analysis will be the program SYSTAT, but introduction to other relevant programs could also be a possibility.
