Both positive and negative results may be expressed with a well defined statistical certainty. Perhaps the best known astrometric study is that of Barnard's star by van de Kamp (1963). That “detection” was later discounted by Gatewood and Eichhorn (1973) but neither study attempted to specify what types (in mass and… Expand
