Folded gaussian distribution
WebLin (2004) used folded normal distribution to study the magnitude of deviation of an automobile strut alignment. Leone, Nelson and Nottingham (1961) have mentioned some more applications of folded normal distribution specially when measuring straightness and flatness of any object. The pdf of univariate folded normal distribution, as proposed ... WebJan 9, 2024 · Theorem: Let X be a random variable following a normal distribution: X ∼ N(μ, σ2). Then, the variance of X is. Var(X) = σ2. Proof: The variance is the probability-weighted average of the squared deviation from the mean: Var(X) = ∫R(x − E(X))2 ⋅ fX(x)dx. With the expected value and probability density function of the normal ...
