In gederajeg/collogetr: Collocates Retriever and Collocation Association Measure for the Indonesian Leipzig Corpora

Description

internal function called by collex_logOR to compute Log10 Odds Ratio (Gries 2014).

Usage

logOR_compute(a, b, c, d)

Arguments

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.

Value

A double-numeric value of Log10 Odds Ratio score

Examples

# Data from Table 2 in Rajeg and Rajeg (2019:71)
a <- 9
b <- 1
c <- 408
d <- 305

logOR_compute(a, b, c, d)

# the above data produces positive log OR
# Observed freq. for cell "a" is larger than the Expected freq.

# Data from Table 3 in Rajeg and Rajeg (2019:74)
a <- 1
b <- 6
c <- 416
d <- 300

logOR_compute(a, b, c, d)

# the above data produces negative log OR
# Expected freq. for cell "a" is larger than the Observed freq.
