Metodología didáctica y sistemas de evaluación

Lectures and practical excercices with the computer, using programs in R.

Temas a desarrollar

Since the type of data analysed by the target audience for this course involves a very high number of compositional parts, the topics to be treated will include the following:

• The use of classical SVD-based methods of dimension reduction, called logratio analysis in this context;
• Clustering of parts as a way to reduce dimensionality;
• Variable selection as a way to reduce dimensionality;
• The problem of zeros in compositional data;
• The correspondence analysis alternative, which can be measurably close to the logratio approach, and which has no problem with data zeros.

The R programming environment will generally be used in the practical part of the workshop. Participants should preferably have their own laptops, with R and RStudio installed.
