The level of differential gene expression may be defined as a fold change, a frequency of upregulation, or some other measure of the degree or extent of a difference in expression across groups of interest. On the basis of expression data for hundreds or thousands of genes, inferring which genes...

and computationally fast alternative we propose a novel shrinkage covariance estimator that exploits the Ledoit-Wolf (2003 …) lemma for analytic calculation of the optimal shrinkage intensity. Subsequently, we apply this improved covariance estimator …
