Sentences with phrase «probability of false positives»

But an alternative is to make statistical calculations for the probability of false positives among these thousands of exoplanet candidates.

The 95 % significance level means that there's only a 1 in 20 chance that the stated finding (RR) does not lie within the stated confidence interval, ie the probability of a false positive is.05.

Not exact matches

One common misinterpretation is that a P value of.05 implies a 95 percent probability that the effect is real (or, in other words, that the chance of a false positive is only 5 percent).

If your goal is a 5 percent risk of a false positive, you need a prior probability of 87 percent when the P value is.05.

«That separation indicates that the probability of random effects causing a false positive match using the CMC method is very low,» said co-author and physicist Ted Vorburger.

Probability of occurrence of the classes of false positives (diluted and undiluted binaries) and of confirmed planets detected by CoRoT, per unit log of transit depth, based on the amplitude found in the original CoRoT light - curve.

«Unequivocal» is merely > 90 % probability, significantly short of the 95 % confidence Trenberth tells us that scientists normally rely upon to avoid false positives.

Out of 7056 KOIs, we determine that 1935 have probabilities < 1 % to be astrophysical false positives, and thus may be considered validated planets.

Abstract: We present astrophysical false positive probability calculations for every Kepler Object of Interest (KOI)-- the first large - scale demonstration of a fully automated transiting planet validation procedure.

The transit signals were detected in photometric data from the Kepler satellite, and were confirmed to arise from planets using a combination of large transit - timing variations, radial - velocity variations, Warm - Spitzer observations, and statistical analysis of false - positive probabilities.

Based on an analysis of the Kepler brightness measurements, along with high - resolution imaging and spectroscopy, Doppler spectroscopy, and (for 11 stars) asteroseismology, we establish low false - positive probabilities for all of the transiting planets (41 of 42 have a false - positive probability under 1 %), and we constrain their sizes and masses.

A promising exoplanet candidate w... ▽ More As is the case for all techniques involved in the research for exoplanets, direct imaging has to take into account the probability of so - called astrophysical false positives, which are phenomena that mimic the signature of objects we are seeking.

No correlation is significant under the Bonferroni correction, which aims at keeping at the probability of one or more false positives and would require (when applied separately to each family of 14 comparisons between one measure of popularity and one C - BARQ variable).

This statistic measures model performance by plotting the sensitivity values — the true positive fraction of test points — against 1 - specificity — the false - positive fraction for all available probability thresholds [53].

Since the possibility space for the existence of major problems is large, calculating probabilities or possibilities of each is sure to lead to false positives.
