`twT` |
A two way table, as produced by |

The entries in the presumed 2 by 2 table are labeled n11, n12, n21, n22, corresponding to the entries in the first row first column, first row second column etc. The odds ratio is the product of n11 and n22 divided by the product of n12 and n21. The Conordance is simply the n11 entry. The Jaccard index is the n11 entry divided by the sum of n11, n12, and n21. Hubert's Gamma is slightly more complicated.

`Concordance ` |
The concordance statistic. |

`Jaccard` |
