<div class="signature">The result I have in Weka is:</div>
<div class="signature"> </div>
<div class="signature">4. potatoes=y beer=y 2 ==> onion=y 2 \
<conf:(1)> lift:(1.5) lev:(0.11) [0] conv:(0.67)</div>
<div class="signature"> </div>
<div class="signature">So I see that there were 2 <span class="tlid-translation \
translation" lang="en"><span title="">bindings</span></span> "potatoes <=> \
beer" in baskets (2 times clients bougth potatoes and beer). And when there were \
such connections, in basket there was also onion.</div>
<div class="signature">So "conf" is 1 because 2/2 = 1 (there will always be \
1 so what is the sense of this "1"?)</div>
<div class="signature"><span class="tlid-translation translation" lang="en"><span \
title="">Do I correctly interpret these numbers</span></span>?</div>
<div class="signature"> </div>
<div class="signature">What is "lift" and how this is calculated? Same \
about "lev" and "conv".</div>
<div class="signature"> </div>
<div class="signature">Regards</div>
