Answer 1

Independently and Identically Distributed:
iid is an abbreviation for "independently and identically distributed." One would say this about two or more random variables to describe their joint distribution. A common use is to describe ongoing disturbances to a stochastic process, indicating that they are not correlated to one another.
簡單說就是各隨機變數間獨立而且具有相同分配
