Distribution of GOF statistics. Residual QQ plots of model fits normalized with the 75% count and no blocking factor. 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) Standard Poisson, B) NB with a global estimate of φ, C) NB with per-gene estimates of φ, D) NB with local estimates of φ. Panels E-H are as in A-D but zoomed in on the bottom left corner of the plots.
