SAVER: gene expression recovery for single-cell RNA sequencing
In single-cell RNA sequencing (scRNA-seq) studies, only a small fraction of the transcripts
present in each cell are sequenced. This leads to unreliable quantification of genes with low …

[HTML][HTML] Bulk tissue cell type deconvolution with multi-subject single-cell expression reference
Abstract Knowledge of cell type composition in disease relevant tissues is an important step
towards the identification of cellular targets of disease. We present MuSiC, a method that …

A modified Bayes information criterion with applications to the analysis of comparative genomic hybridization data
NR Zhang, DO Siegmund - Biometrics, 2007 - academic.oup.com
In the analysis of data generated by change-point processes, one critical challenge is to
determine the number of change-points. The classic Bayes information criterion (BIC) statistic …

[HTML][HTML] BRCA locus-specific loss of heterozygosity in germline BRCA1 and BRCA2 carriers
Complete loss of BRCA1 or BRCA2 function is associated with sensitivity to DNA damaging
agents. However, not all BRCA1 and BRCA2 germline mutation-associated tumors respond. …

Assessing intratumor heterogeneity and tracking longitudinal and spatial clonal evolutionary history by next-generation sequencing
Cancer is a disease driven by evolutionary selection on somatic genetic and epigenetic
alterations. Here, we propose Canopy, a method for inferring the evolutionary phylogeny of a …

Bayesian variable selection in structured high-dimensional covariate spaces with applications in genomics
… We follow the approach suggested in Zhang, Wildermuth, and Speed (2008) and use the
scores of the first principal component of the data, the loadings of which are plotted versus time …
