internal function called by collex_logOR to compute Log10 Odds Ratio (Gries 2014).
logOR_compute(a, b, c, d)
| a | co-occurrence frequency between a given collocate and the nodeword. |
|---|---|
| b | co-occurrence frequency between the collocate and other words. |
| c | co-occurrence frequency between the nodeword and the other words. |
| d | co-occurrence frequency between all other words. |
A double-numeric value of Log10 Odds Ratio score
