Coparison between Gini index and Fano factor in detecting differentially expressed genes. a Scaled density plot of the expression levels of genes X (red) and Y (blue). The proportion of the minor cell type is 50 %. b The Lorenz curve for genes X (red) and Y (blue). The proportion of the minor cell type is 50 %. c, d Same as (a, b), except the proportion of the minor cell type is changed to 1e-5. e Fano factor for genes X and Y for varying proportions of the minor cell type (1/1 M stands for one in one million). f Gini index for genes X and Y for varying proportions of the minor cell type
