A case when some data is not precise is considered, and observation are described by possibility distributions over a set of categories of one variable. For such data the fuzzy gamma statistic was defined, and the method­ology for the statistical inference related to this fuzzy measure of dependence was presented.}, title={Goodman-Kruskal γ measure of dependence for fuzzy ordered categorical data}, type={Text}, URL={http://www.rcin.org.pl/Content/103566/PDF/RB-2004-10.pdf}, keywords={Fuzzy preferences, Rozmyte preferencje}, }
