1) the joint distributions FX1 ,X2 ,··· ,Xn satisfy lim FX1 ,X2 ,··· ,Xn (x1 , x2 , . . 36) for i ∈ {1, 2, . . , n} and fixed xj , j ∈ {1, 2, . . , i − 1, i + 1, . . , n}. ,xn →+∞ FX1 ,X2 ,··· ,Xn (x1 , x2 , . . , xn ) = 1. 37) 46 1 Preliminaries from Probability Theory In addition, FX1 ,X2 ,··· ,Xn is non-decreasing and continuous from the right in xi for i ∈ {1, 2, . . , n}. For any permutation {i1 , i2 , . . , in } of the set {1, 2, . . , n} we have FXi1 ,Xi2 ,··· ,Xin (xi1 , xi2 , . .

Y˜m ) ∼ Nm (0, A−1 B D B (A−1 ) ) turns out to be an m-dimensional Gaussian vector with zero mean vector and standard variances for its components. Therefore, it follows for y ˜ = (˜ y1 , y˜2 , . . , y˜m ) = A−1 y that P Y˜i < y˜i , i ∈ {1, 2, . . , m} = P (Yi < yi , i ∈ {1, 2, . . 50). 54) for any vectors θ, x ∈ n . This yields the multivariate Gaussian shift property for X ∼ Nn (0, D), a deterministic vector θ = (θ1 , θ2 , . . , θn ) and a scalar function H(x) of an n-dimensional vector x = (x1 , x2 , .

Properties of Independent Random Variables Recall the definition of independent random variables in Sect. 1. 22) 44 1 Preliminaries from Probability Theory for all x1 , x2 ∈ . 23) for all measurable functions g1 , g2 for which the above expectations exist. If both FX1 and FX2 have density functions fX1 and fX2 , respectively, and if X1 and X2 are independent, then their joint distribution function FX1 ,X2 has a density function fX1 ,X2 which satisfies the equation fX1 ,X2 (x1 , x2 ) = fX1 (x1 ) fX2 (x2 ).
