WebOct 13, 2015 · A more straightforward and general way to calculate these kinds of integrals is by changing of variable: Suppose your normal distribution has mean μ and variance σ 2: N ( μ, σ 2) E ( x) = 1 σ 2 π ∫ x exp ( − ( x − μ) 2 2 σ 2) d x now by changing the variable y = x − μ σ and d y d x = 1 σ → d x = σ d y. The normal distribution is the only distribution whose cumulants beyond the first two (i.e., other than the mean and variance) are zero. It is also the continuous distribution with the maximum entropy for a specified mean and variance. Geary has shown, assuming that the mean and variance are finite, that the normal distribution is the only distribution where the mean and variance calculated from a set of independent draws are independent of each other.
