Conditionally independent统计学
WebAn X two are not independent. So P does not satisfy. X one is independent of X2. But we have that P does satisfy. X one is independent of x two given c. So here's a very simple and intuitive example of contuitive independence. Let's go back to con, another example of conditional independence, one in the distribution that we've seen before. WebIt is possible for something to be statistically independent and not conditionally independent. To borrow from Wikipedia: if A and B both take the value 0 or 1 with 0.5 …

(iii)Random elements Xi, i 2I, are said to be independent iff s(Xi), i 2I, are independent. Lemma 1.3 (a useful result for checking the independence of s-fields) Let Ci, i 2I, be independent collections of events. If each C iis a p-system (A2C and B 2C implies A\B 2C ), then s(Ci), i 2I, are independent.
