2. 21. Computer-intensive methods for dependent observations

   Author : Anders Nordgaard; Rainer Dahlhaus; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : This dissertation deals with computer-intensive methods for dependent observations. The main part is built up by four papers defining and analyzing a resampling method of bootstrap type for the spectral domain of a stationary Gaussian sequence. The emphasis is on practical aspects as well as on asymptotic validity. READ MORE

4. 22. Clades in the "higher land bird assemblage"

   Author : Ulf. S. Johansson; Scott V. Eswards; Stockholms universitet; []

   Abstract : This thesis summarizes the results of several phylogenetic studies of birds included in the “higher land bird assemblage” (Anomalogonatae sensu Beddard 1898). The phylogenetic analyses are primarily based on gene sequences obtained from the nuclear genome (exons of the c-myc and RAG-1 genes and an intron of the myoglobin gene). READ MORE

   Abstract : Abstract syntax trees are an alternative representation to syntactic structures commonly found in NLP systems. This representation allows for sharing of structures across languages, making it well suited to serve as a translation interlingua. READ MORE

6. 24. Network models with applications to genomic data: generalization, validation and uncertainty assessment

   Author : José Sánchez; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Inverse covariance matrix; precision matrix; graphical models; high-dimension; low-sample; networks; sparsity; fused lasso; elastic net; cancer; TCGA pan cancer analysis; online resource; discriminant analysis; classification; networks;

   Abstract : The aim of this thesis is to provide a framework for the estimation and analysis of transcription networks in human cancer. The methods we develop are applied to data collected by The Cancer Genome Atlas (TCGA) and supporting simulations are based on derived models in order to reflect real data structure. READ MORE
