Estimation of variances and covariances is required for many statistical methods such as t‐test, principal component analysis and linear discriminant analysis. High‐dimensional data such as gene expression microarray data and financial data pose challenges to traditional statistical and computational methods. In this paper, we review some recent developments in the estimation of variances, covariance matrix, and precision matrix, with emphasis on the applications to microarray data analysis.
