Community detection is the process of grouping strongly connected nodes in a network. Many community detection methods for un-weighted networks have a theoretical basis in a null model, which provides an interpretation of resulting communities in terms of statistical significance. In this paper, we introduce a null for sparse weighted networks called the(More)
Expression Quantitative Trait Loci (eQTL) detection is the task of identifying regulatory relationships between genes and genomic loci. Often, this is performed through a multiple testing procedure, where individual tests are based on regression p-values for gene-SNP pairs. Due to the non-Normality of residuals when raw gene expression data is used,(More)
Multilayer networks are a useful way to capture and model multiple, binary relationships among a fixed group of objects. While community detection has proven to be a useful exploratory technique for the analysis of single-layer networks, the development of community detection methods for multilayer networks is still in its infancy. We propose and(More)
