Illustration of how changing the tag formation probability φ affects the posterior marginal distributions under two different scenarios: (a) when no tags are observed for a particular gene and (b) when ten tags are observed for a particular gene. In (a) where no tags are observed, the posterior mode occurs on the boundary of the parameter space and changing φ has no effect on the mode. Increasing φ does, however, decrease the width of the distribution. In (b) where ten tags are observed, increasing φ leads to a decrease in the mode and also decreases the absolute width of the distribution (which is indicated on the log scale by shifting to the left).
