Distribution of GOF statistics when experimental factors are included in the model. QQ plots of model fits with the NB distribution, local estimates of φ and 75th percentile count offset including blocking factors as indicated. Tick-marks along the top indicate deciles. The top 5% of GOF statistics are indicated in alternate colors with the top 1% being red and the next 4% being blue. A) lane-pair, B) library preparation batch, C) flow cell. Panel D is the same as A, but zoomed in on the bottom left corner of the plot; no zoom is needed for panels B and C.
