A general framework for estimating the relative pathogenicity of human genetic variants

- Martin Kircher, D. Witten, P. Jain, B. O’Roak, G. Cooper, J. Shendure
- Biology, Medicine
- Nature Genetics
- 2 February 2014

Current methods for annotating and interpreting human genetic variation tend to exploit a single information type (for example, conservation) and/or are restricted in scope (for example, to missense… Expand

- 1 July 2009

We present a penalized matrix decomposition (PMD), a new framework for computing a rank-K approximation for a matrix. We approximate the matrix X as circumflexX = sigma(k=1)(K) d(k)u(k)v(k)(T), where… Expand

The joint graphical lasso for inverse covariance estimation across multiple classes.

- 1 November 2011

We consider the problem of estimating multiple related Gaussian graphical models from a high-dimensional data set with observations belonging to distinct classes. We propose the joint graphical… Expand

A Framework for Feature Selection in Clustering

- D. Witten, R. Tibshirani
- Medicine, Mathematics
- Journal of the American Statistical Association
- 1 June 2010

We consider the problem of clustering observations using a potentially large set of features. One might expect that the true underlying clusters present in the data differ only with respect to a… Expand

Extensions of Sparse Canonical Correlation Analysis with Applications to Genomic Data

- D. Witten, R. Tibshirani
- Computer Science, Mathematics
- Statistical applications in genetics and…
- 2009

In recent work, several authors have introduced methods for sparse canonical correlation analysis (sparse CCA). Suppose that two sets of measurements are available on the same set of observations.… Expand

Penalized classification using Fisher's linear discriminant.

- D. Witten, R. Tibshirani
- Medicine, Mathematics
- Journal of the Royal Statistical Society. Series…
- 1 November 2011

We consider the supervised classification setting, in which the data consist of p features measured on n observations, each of which belongs to one of K classes. Linear discriminant analysis (LDA) is… Expand

CADD: predicting the deleteriousness of variants throughout the human genome

- Philipp Rentzsch, D. Witten, G. Cooper, J. Shendure, Martin Kircher

Abstract Combined Annotation-Dependent Depletion (CADD) is a widely used measure of variant deleteriousness that can effectively prioritize causal variants in genetic analyses, particularly highly… Expand

Hierarchical maintenance of MLL myeloid leukemia stem cells employs a transcriptional program shared with embryonic rather than adult stem cells.

- 6 February 2009

The genetic programs that promote retention of self-renewing leukemia stem cells (LSCs) at the apex of cellular hierarchies in acute myeloid leukemia (AML) are not known. In a mouse model of human… Expand

New Insights and Faster Computations for the Graphical Lasso

- Mathematics
- 1 January 2011

We consider the graphical lasso formulation for estimating a Gaussian graphical model in the high-dimensional setting. This approach entails estimating the inverse covariance matrix under a… Expand
