[Corpora-List] Chi-Square

[Marco Baroni]

You can see the comparison of chi-square and log-likelihood ratio in this 
famous paper, that I think was very influential in giving the Chi-square 
test a bad name:

T. Dunning, "Accurate Methods for the Statistics of Surprise and 
Coincidence," Computational Linguistics 19(1), 1993.

The paper is quite mathematical, but the basic idea and the empirical 
comparison part should be quite clear... (although the alternative to 
chi-square should be something like the log-likelihood ratio test, not MI, 
that has the same problem of overestimation of the significance of the 
co-occurrence of rare words that the chi-square test has...)
