The total exoplanet tally now stands at about 3,200, and Kepler has found 2,235 of them
False positive probabilities for all Kepler objects of interest: 1284 Newly validated planets and 428 likely false positives.(20 pages paper)
Out of 7056 KOIs (Kepler Objects of Interest), researchers determine that 1935 have probabilities less than 1% to be astrophysical false positives, and thus may be considered validated planets. 1284 of these have not yet been validated or confirmed by other methods. In addition, we identify 428 KOIs likely to be false positives that have not yet been identified as such, though some of these may be a result of unidentified transit timing variations. A side product of these calculations is full stellar property posterior samplings for every host star, modeled as single, binary, and triple systems. These calculations use vespa, a publicly available Python package able to be easily applied to any transiting exoplanet candidate.
