Sampling is a process which take a small part of data from origin dataset.
Statistic is different.It use maths model to evaluate data.

【 在 jimo (寂寞) 的大作中提到: 】
: 呵呵   ar 里的sampling 和统计还是有关系的
: 【 在 sinokdd (KDD in China) 的大作中提到: 】
: : Yeah, but data mining is not association rule or sequential pattern only.
: : If you only know AR or SP, I am sure there is very little thing
: : you can do for data mining.
: : And actually data mining is borrowed from statistics, and of course you can
: : say that AR is nothing to do with statistics.
: : The definition of KDD is the process of pattenr discovery from large data,
: : the mostly used techiques are from machine learning and statistics. And now
: : people donot care what technology you use in mining, but if you can get some
: : patterns, not the original data itself, then you can call the process as
: : data mining.
