Draft by Dr. Guan Koh 6/14/1997
NOTE: This is a draft and not entirely complete.
Survival Statistics may be slightly higher in the U.S.
It is my (Olga) opinion that the zero values should not
taken as an absolute, but rather assume a <1% value;
Same thing with the 100%; assume 99%.
"There's no such thing as a sure thing"
