MI Score _{[ statistics ]}

The Mutual Information score expresses the extent to which words co-occur compared to the number of times they appear separately. MI Score is affected strongly by the frequency, low-frequency words tend to reach a high MI score which may be misleading. This is why Sketch Engine allows setting a frequency limit so that low-frequency words can be excluded from the calculation. In most cases T-score is more useful than MI score. see Concordance - Collocations see Statistics in Sketch Engine compare T-score
minimum sensitivity _{[ statistics ]}
a statistics measure similar to logDice which is the minimum of the two following numbers:
- the number of co-occurrences divided by the frequency of the collocate
- the number of co-occurrences divided by the frequency of the node word
The minimum sensitivity number grows with a high number of co-occurrences and falls with a high number of occurrences of the individual words (node word or collocate).
