Expression variability (EV) in human breast, cerebellum, and frontal cortex tissue. (a) Expected expression MAD for curve as a function of median probe expression (solid black line). (b) Kernel density estimation function of EV. The vertical black lines represent the EV classification ranges. (c) Expression variability as a function of median gene expression. Adjusted R2 values for the linear regression model shown in red were 0.0002, 0.0008, and 0.005 and the associated Kendall rank correlation coefficients were − 0.208, − 0.201, − 0.213 for breast, cerebellum, and frontal cortex tissues respectively
