For mapping and exploring communities of both micro- and macro-organisms, high throughput sequencing (HTS) of environmental DNA has become a powerful approach. This can be done either through DNA-metabarcoding, focusing on a single marker, or DNA-metagenomics/metatranscriptomics, dealing with sequencing of all DNA/RNA in the samples.

_{Weekly Theory Seminar.}

This course aims to prepare researchers to be supervisors either at an early supervisor stage or before entering the role and is tailored for young researchers in biotechnology and life sciences.

Variable selection methods based on L₀ penalties have excellent theoretical properties to select sparse models in a high-dimensional setting. There exist modifications of BIC which either control the family wise error rate (mBIC) or the false discovery rate (mBIC2) in terms of which regressors are selected to enter a model. However, the minimization of L₀ penalties comprises a mixed integer problem which is known to be NP hard and therefore becomes computationally challenging with increasing numbers of regressor variables. This is one reason why alternatives like the LASSO have become so popular, which involve convex optimization problems which are easier to solve. The last few years have seen some real progress in developing new algorithms to minimize  L₀ penalties. We will compare the performance of these algorithms in terms of minimizing L₀ based selection criteria.
Simulation studies covering a wide range of scenarios which are inspired by genetic association studies are used to compare the values of selection criteria obtained with different algorithms. Additionally some statistical characteristics of the selected models and the runtime of algorithms are compared.
