Most importantly, we also quantify and characterize the distribution and rate of occurrence of planets down to Earth size with no prior assumptions on their frequency, by subtracting from the population of actual Kepler candidates our simulated population of astrophysical false positives.

By comparing their distribution with that of the Kepler Objects of Interest detected during the first six quarters of operation of the spacecraft, we infer the false positive rate of Kepler and study its dependence on spectral type, candidate planet size, and orbital period.

For models, such as SMR, where the distribution of the model parameters is unknown, permutation test and stability selection are typically used to control for false positives.

For the LTQ - Orbitrap Velos data, the distribution of mass deviation (from the theoretical masses) was first determined as having a standard deviation (σ) of 2.05 part per million (ppm), and a mass error of smaller than 3σ was used in combination with Xcorr and ΔCn to determine the filtering criteria that resulted in < 1 % false positive peptide identifications.

Figures 1a and 1b focus on misclassification at the bottom of the teacher performance distribution, but the false positive / false negative tradeoff arises with any classification system.
