NettetLinearity of Expectation Linearity of expectation basically says that the expected value of a sum of random variables is equal to the sum of the individual expectations. Its … The basic properties below (and their names in bold) replicate or follow immediately from those of Lebesgue integral. Note that the letters "a.s." stand for "almost surely"—a central property of the Lebesgue integral. Basically, one says that an inequality like is true almost surely, when the probability measure attributes zero-mass to the complementary event . • Non-negativity: If (a.s.), then .

NettetLinearity. Expectation is a linear operator: (5.58) where {a, b} are constant coefficients. Nonnegative. If X is nonnegative such that P (X <0) = 0, then because . Symmetry. If there exists a value μ about which the pdf is symmetric, which is the case for a Gaussian random variable, then μ is the expected value (the mean). NettetThis is known as linearity of expectation, and holds even when the random variables X_i X i are not independent events.
