Semisupervised estimation of parameters. Semisupervised estimation of parameters of the same distribution of scores as in
Figures 2b and 2a. For Charge 3 the slight rightward shift of the Gamma distribution
(distribution of scores for incorrect identifications) also encouraged a large rightward
shift of the Normal Distribution (distribution of scores for correct identifications).
The two vertical lines indicate the means of the Normal distributions. The addition
of decoys for Charge 2 allowed to algorithm to learn that most of the identified spectra
with scores from 0 to 1 are likely to be incorrect. Without decoys this may have been
overlooked.
