Mean and variance of folded normal
WebIn probability theory and statistics, the half-normal distribution is a special case of the folded normal distribution . Let follow an ordinary normal distribution, . Then, follows a half … WebThe standard normal distribution has zero mean and unit standard deviation. If z is standard normal, then σz + µ is also normal with mean µ and standard deviation σ . Conversely, if x is normal with mean µ and standard deviation σ, then z = ( x – µ ) / σ is standard normal. Parameter Estimation

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.
