Both the MI score and the t-score have their limitations. MI computes a logarithm representing the number of co-occurrences of words compared to their occurrences apart in the corpus, which can highlight rare collocations if the components tend not to occur with other words. The t-score formula is less susceptible to this but its numerical result cannot be meaningfully compared across corpora of different sizes.
