Fig. 2From: Hierarchicell: an R-package for estimating power for tests of differential expression with single-cell datatSNE plots of gene expression data simulated to correlate with a continuous variable. The continuous phenotype is simulated with normal with a mean of 22 and standard deviation of 5 and correlates at various levels with gene expression. In the top left panel, the correlation between gene expression and the simulated phenotype is 0.99. In the top right it is 0.67, on the bottom left it is 0.33, and on the bottom right it is 0.01Back to article page
