Fig. 7From: Fast and robust imputation for miRNA expression data using constrained least squaresExample multivariate normal data sets for varying R, when \(p=2\). The two classes are highlighted in blue and red in each case. Here, \(R\sim 1\) means \(R=1-10^{-6}\). Note, R cannot be exactly 1 as then C would not be positive definiteBack to article page
