[Corpora-List] Fisher exact tests

[Stefan Th. Gries]

Hi everybody

For a current project involving collocations, a colleague and I need to
compute several hundreds of F-E tests, some of which involve very high
marginal totals even though the cooccurrence frequencies are very small. The
question now is, do you happen to know of any
(Windows/Macintosh/Linux-based)software that can cope with the enormous
sizes of the resulting figures? An example:
2    3    5
1,584    10,204,711    10,206,295
1,586    10,204,714    10,206,300

Some scripts on the web seemed to do the job, but on second looks, the
results seemd wrong because transforming tables (along the main diagonal)
with such high figures lead to different results, inviting the inference
that the scripts only computed approximations ... Any idea(s)?
