Computing mutual information statistics for collocationHow mutual information scores are computed?Please refer to http://www.umiacs.umd.edu/users/resnik/nlstat_tutorial_summer1998/Lab_ngrams.html for computing procedure and formula. How to interpret mutual information scores?The following guidelines can be used:
If the scores are high or medium, the collocation strength is strong. If MI is below 1, it is less likely that the two tokens are related. MI scores between 1 and 3 are in the gray area.

Other statistical measures of collocationOther statistical measures such as tscore, likelihood ratio, chisquare and Yule's Y are often used to measure collocation strength. For an introduction and comparison of those measures, please refer to, among others:
