统计不仅仅是一们科学, 更是一个人生观. 生活中的点点滴滴都可一用distribution和统计理论来解释 with some ASSUMPTIONS. I do not expect everyone can understand and apply it. 就是我身边学统计的, 也没几个可以把生活中的一些事用统计理论来解释. But I think I have explained myself pretty clear with several posts here. I am going to withdraw myself from the discussion since it seems meaningless to continue. "清者自清, 浊者自浊"说得真好......so peace out.
