<P><FONT SIZE=2>Hi,<BR>
<BR>
I retrieved the formula for the unorthodox MI score for spans greater than 2.<BR>
<BR>
MI = log2( N^(s-1) * f(abc...) / (f(a)*f(b)*f(c)...))<BR>

I've just heard from Michael Barlow. His Collocate software uses the <BR>
Log 2 formula:<BR>
<BR>
N · f (x y)<BR>
=log2 __________________<BR>
f (x) · f (y)<BR>
<BR>
Best,<BR>
