WebRegarding the general form of the mean of the absolute value of a Normal ( μ, σ 2): Following @Henry's link to Wikipedia's article on the half-normal, I found that there is now a page for the so-called "Folded normal distribution", which is an extension of the half-normal for μ ≠ 0. • The distribution is a special case of the folded normal distribution with μ = 0. • It also coincides with a zero-mean normal distribution truncated from below at zero (see truncated normal distribution) • If Y has a half-normal distribution, then (Y/σ) has a chi square distribution with 1 degree of freedom, i.e. Y/σ has a chi distribution with 1 degree of freedom.
WebIf a Normal distribution having mean = 0 is truncated from below at 0, it is (the same as) a half-Normal distribution.

It was used to model brownian movement and can also be used in the modeling measurement data and lifetime data. Let X~N(0,σ2), then Y = X follows half normal distribution. The ...

For instance, introduced in [9] is an economic model to determine the process specification limits for … WebJan 1, 2013 · Leone et al. (1961) proposed the folded-normal (FN) distribution when the measurement system produces only non-negative measurements from a normally distributed process. When the location ...
The folded normal distribution is a probability distribution related to the normal distribution. Given a normally distributed random variable X with mean μ and variance σ , the random variable Y = X has a folded normal distribution. Such a case may be encountered if only the magnitude of some variable is recorded, but not its sign. The distribution is called "folded" because probability mass to …
