Fig. 2From: iDESC: identifying differential expression in single-cell RNA sequencing data with multiple subjectsEmpirical type I error of all methods on the two permuted real datasets. Boxplots showing the median (center line), interquartile range (hinges), and 1.5 times the interquartile (whiskers) of empirical type I error at the nominal level of 0.05. Confidence interval of type I error is marked by two dashed lines (0.031–0.069)Back to article page
