International Economic Review. 35: 705–730. Remark II: The ordinary Weibull distribution arises in reliability applications and is obtained from the distribution here by using the variable t = μ − x {\displaystyle t=\mu -x} , which However this is not a standard nomenclature. Both families add a shape parameter to the normal distribution.

A generalized normal distribution with Β = 1/2 is equal to the normal distribution; if Β = 1 it is equal to the Double Exponential or Laplace distribution.

the product of n {\displaystyle n} exponential power distributions with the same β {\displaystyle \beta } and α {\displaystyle \alpha } parameters, is the only probability density that can be written Support x ∈ [ μ − σ / ξ, +∞) when ξ > 0, x ∈ (−∞, +∞) when ξ = 0, x ∈ (−∞, μ − σ / ξ ] when ξ < Discrete vs. For example, the lognormal, folded normal, and inverse normal distributions are defined as transformations of a normally-distributed value, but unlike the generalized normal and skew-normal families, these do not include the

Leadbetter, M.R., Lindgren, G. These values for m {\displaystyle m} and v {\displaystyle v} yield a distribution with mean of μ {\displaystyle \mu } if p q > 1 {\displaystyle pq>1} and a variance of

Large values of p {\displaystyle p} and q {\displaystyle q} yield a distribution that is more platykurtic. doi:10.2307/2527081.

"A practical procedure to estimate the shape parameter in the generalized Gaussian distribution" (PDF). Michelfelder, and P. By the extreme value theorem the GEV distribution is the only possible limit distribution of properly normalized maxima of a sequence of independent and identically distributed random variables.

Expected Value 9. Since the sample space (the set of real numbers where the density is non-zero) depends on the true value of the parameter, some standard results about the performance of parameter estimates Properties[edit] The multivariate generalized normal distribution, i.e. Journal of Applied Statistics. 32 (7): 685–694.

Vasanthat Kumari describe these classes as: Generalized Error Distributions of the first kind (GED-1). Wright (Ed.), Sea Level Rise, Coastal Engineering, Shorelines and Tides, Chapter-14, pp. 269–276. For ξ = 0 {\displaystyle \xi =0} the expression just given for the cumulative distribution function is formally undefined and is replaced by the result obtained by taking the limit as Maximum likelihood estimator[edit] It is possible to fit the generalized normal distribution adopting an approximate maximum likelihood method.[4][5] With μ {\displaystyle \mu } initially set to the sample first moment m

Positive values of the shape parameter yield left-skewed distributions bounded to the right, and negative values of the shape parameter yield right-skewed distributions bounded to the left. In the first case, at the lower end-point it equals 0; in the second case, at the upper end-point, it equals 1. Am. 86: 1404–1415.
