International Economic Review. 35: 705â€“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.

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): 685â€“694.

Vasanthat Kumari describe these classes as: Generalized Error Distributions of the first kind (GED-1).

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: 1404â€“1415.
