<Robert Tibshirani> develops methods for statistical learning and <biostatistics>, with applications to <genomics> and medicine. His Stanford research profile connects methodological work with scientific data and computational tools.https://statistics.stanford.edu/people/robert-tibshirani[Institutional research description]{ref}
With <Jerome H. Friedman> and <Trevor Hastie>, he developed the <Graphical Lasso> for estimating a sparse <precision matrix>. An absolute-value penalty encourages zero entries, which encode <conditional independence> relationships in a <multivariate normal distribution>. The method combines a statistical model with an efficient optimization algorithm.<Sparse inverse covariance estimation with the graphical lasso by Jerome H. Friedman and others>[Abstract and penalized likelihood formulation]{ref}
