$PR$ is the estimated population proximity-ratio.   Note that we can use $PR$ in place of $E$ since the detected counts are partitioned   between donor and acceptor channels according to a binomial distribution with   a $p$ parameter equal to *PR* $PR$  (regardless of the molecular FRET efficiency $E$). The only approximation done here is neglecting the presence background  (a reasonable approximation since the backgrounds counts are in general a   very small fraction of the total counts).
