[Spambayes] runratio with timcv.py

[Brad Clements]

Hmm,

Well I didn't get tim's message about "using timcv.py for incremental is bad" until after I 
started my ratio testing.

This is timcv.py on -n 10 with 1200 messages total per set.

use_central_limit: True

I also have timtest.py running, I have no idea if runratio.sh will handle it's output.. Will 
post when that finishes running.

Also, I modified runratio.sh to handle arbitrary list of spam/ham count steps.. want me 
to post?


(last stat line)
-> <stat> tested 1050 hams & 150 spams against 9450 hams & 1350 spams

And the table
