For example, for a joint occurrence of two singletons in 500,000 samples, G 2 is approximately 28.24.
if we wanted to use G 2 as our measure of association, we could compare the number of word pairs expected by chance to have a G 2 score greater than or equal to 28.24 with the number of word pairs observed to have a G 2 score greater than or equal to 28.24, and compute expected noise and precision just as we did with p-values.
