Sean Owen commented on MAHOUT-563:
----------------------------------
Couple other things... careful about Double.MIN_VALUE. It's not the most
negative value -- it's actually the smallest positive double.
Double.NEGATIVE_INFINITY is the right one.
t1Found/t2Found are set in setStarterValues(), but not used in estimate?
Also it's possible that subSample() never terminates if the input had any nulls.
We might want to back up and discuss this a little more...

> Hunting for T1/T2 values that make an interesting Canopy set is a singularly
