CoCiteStats (version 1.44.0)

twTStats: Computes 3 two way table statistics.

Description

For two way tables based on co-citations four different test statistics are reported, the odds ratio, the Concordance, the Jaccard index and Hubert's Gamma.

Usage

twTStats(twT)

Arguments

twT
A two way table, as produced by twowayTable.

Value

Concordance
The concordance statistic.
Jaccard
The Jaccard index.
Hubert
Hubert's Gamma
OddsRatio
The odds ratio.

Details

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.
