Pairwise distinct 数学

Pairwise independence does not imply mutual independence, as shown by the following example attributed to S. Bernstein. Suppose X and Y are two independent tosses of a fair coin, where we designate 1 for heads and 0 for tails. Let the third random variable Z be equal to 1 if exactly one of those coin tosses resulted in "heads", and 0 otherwise (i.e., ). Then jointly the triple (X, Y, Z) has the following probability distri… WebNov 5, 2024 · 2 pairwise 算法. Pairwise是 L. L. Thurstone (29 May1887 – 30 September 1955)在1927年首先提出来的。. 他是美国的一位心理统计学家。.
