In sylvainloiseau/wam: Word Association Measures

Description

Word association measures give an information about the tendency of two words to co-occurr with greater (or lesser) than chance frequency.

t-score = prob(X=chemistry, Y=physics) - ( prob(X=chemistry) prob(Y=physics) ) ---------------------------------------------------------------------- sqrt((1/T) prob(X=chemistry, Y=physics))

Usage

wam.jaccard(N, n, K, k)

wam.MI(N, n, K, k)

wam.frequency(N, n, K, k)

wam.loglikelihood(N, n, K, k, p.value = FALSE, two.sided = TRUE)

wam.collostruction(N, n, K, k)

wam.specificities(N, n, K, k, method = "log")

wam.z(N, n, K, k, yates.correction = FALSE)

wam.t(N, n, K, k)

wam.chisq(
  N,
  n,
  K,
  k,
  yates.correction = TRUE,
  p.value = TRUE,
  two.sided = FALSE
)

wam.ar(N, n, K, k)

wam.g(N, n, K, k)
