Box and whiskers plot of cell cycle deviance ratio in ranked and unranked genes.

<p>The proportion of stochastic variability in the Hurdle Model explained by cell cycle is shown on the primary y-axis (left) for <i>ranked</i> and <i>unranked</i> genes, with box giving the 25^th, 50^th and 75^th percentiles, and whiskers showing 1.5 times the inter-quartile range. The deflated scale on the secondary y-axis (right) shows the deviance as a percentage of the most completely explained gene (TOP2A, 27%) and is intended as an upper bound for the amount of remaining biological deviance in non-cell-cycle genes. Under this conservative rescaling, cell cycle explains only 25% of the deviance in 75% of unranked genes.
