<François Fressin> led a study of false positives in <Kepler space telescope> transit candidates. A background or physically associated <eclipsing binary> can mimic the dimming attributed to an <exoplanet transit>, so counting candidates alone does not determine <exoplanet occurrence rates>.
The 2013 study simulated these contaminating systems and compared their predicted distribution with the observed candidates. It estimated how the contamination depends on stellar type, apparent planetary size and <orbital period>. This makes false-positive modeling part of the population inference, alongside the probability that a genuine <planet> would be detected.<The false positive rate of Kepler and the occurrence of planets by François Fressin and others>[Abstract: simulated eclipsing-system contaminants, candidate vetting and inferred false-positive rates]{ref}
