I see -- in my blissful ignorance, I know this under the nickname of the exponential power distribution. The system returned: (22) Invalid argument The remote host or network may be down. weblink

It includes all Laplace distributions, and as limiting cases it includes all continuous uniform distributions on bounded intervals of the real line. Some authors refer to this as kurtosis, as kurtosis determines how peaked or how flat the distribution is. Properties[edit] The multivariate generalized normal distribution, i.e. Special Cases:

GED becomes a normal distribution. GED approaches uniform distribution. GED exhibits the highest excess-kurtosis (3). check my bloglog a logical; if TRUE, densities are given as log densities. For more details, view our FAQ. Popular **Articles 1.**

A symmetric distribution which can model both tail (long and short) and center behavior (like flat, triangular or Gaussian) completely independently could be derived e.g. Beta provides you the chance to obtain different distributions just modifying its value, for example if you use beta equals to 2 you obtain a Gaussian distribution (excess of Kurtosis = doi:10.1080/02664760500079464. ^ Varanasi, M.K.; Aazhang, B.

Transaction on Image Processing. 11: 146–158. Generalized Normal Distribution R Remarks The generalized error distribution is also known as the exponential power distribution. Here are the instructions how to enable JavaScript in your web browser. The domain of the p.d.f.

If other deviations from the normal distribution are being studied, other families of distributions can be used. Continuous Variables 8. Skewed Generalized Error Distribution Due to the central role of the normal distribution in probability and statistics, many distributions can be characterized in terms of their relationship to the normal distribution. Error Distribution Definition x, q a numeric vector of quantiles.

This family allows for tails that are either heavier than normal (when β < 2 {\displaystyle \beta <2} ) or lighter than normal (when β > 2 {\displaystyle \beta >2} ). have a peek at these guys The t distribution, unlike this generalized normal distribution, obtains heavier than normal tails without acquiring a cusp at the origin.

You could try to use GEDinv(p,alpha,beta) jointly with Monte Carlo simulation for p and than plot the results to have graphical evidences of what above exposed.
