Publisher's Note: Correction to Equation

Posted by PLOS_CompBiol on 11 Jul 2008 at 14:35 GMT

The Forward score distribution is predicted to converge to an exponential with λ = log 2, with the approximation holding above some score threshold τ:

In the Results section, under the “Local Forward Scores Follow Exponential Tails with Constant λ” heading, the first equation was incorrect. The correct equation is:
P(F>t) \propto e^{-\lambda t - \tau)}, as seen here: http://www.ploscompbiol.org/corrections/pcbi.1000069.cn.pdf
