Example of Benjamini & Hochberg Method
--------------------------------------
Figure 4.6.

Illustration of the Benjamini and Hochberg method for 106 points drawn from
the distribution shown in figure 4.5. The solid line shows the cumulative
distribution of observed p values, normalized by the sample size. The dashed
lines show the cutoff for various limits on contamination rate
:math:`\varepsilon` computed using eq. 4.44 (the accepted measurements are
those with p smaller than that corresponding to the intersection of solid and
dashed curves). The dotted line shows how the distribution would look in the
absence of sources. The value of the cumulative distribution at p = 0.5 is
0.55, and yields a correction factor :math:`\lambda = 1.11` (see eq. 4.46).
