9. 기댓값, 지시확률변수와 선형성 (Expectation, Indicator Random Variables, Linearity)
본 글은 Havard University Statistics 110 강의를 듣고 정리한 내용입니다. CDF : F(x) = P(X ≤ x), x ∈ R Find P(1 P(a 0 as X -> -∞, F(X) -> 1 as x -> ∞ Independent of random variables X, Y are indep r.v.s if P(X≤x, Y≤y) = P(X≤x)P(Y≤y) for all x, y Discrete case: P(X=x, Y=x) = P(X=x)P(Y=y) Averages(Means, Expected va..
