[Corpora-List] Surprisingly large MI scores

[mi.barlow at auckland.ac.nz]

Hi,

I retrieved the formula for the unorthodox MI score for spans greater than 2.

MI = log2( N^(s-1) * f(abc...) / (f(a)*f(b)*f(c)...))

I've just heard from Michael Barlow. His Collocate software uses the  
Log 2 formula:

           N · f (x y)
  =log2  __________________
            f (x) · f (y)

Best,
Brett
