Abstract: Although usually taken as a symmetric measure, G is shown to be a directional coefficient of association. The direction in G is not related to rows or columns of the cross-table nor the identity of… read more here.

DOI: 10.3758/s13428-018-1125-5
Abstract: For decades, researchers have debated the relative merits of different measures of people’s ability to discriminate the correctness of their own responses (resolution). The probabilistic approach, primarily led by Nelson, has advocated the Goodman–Kruskal gamma… read more here.
