ExtremeValueDistribution
Extreme value probability distribution object
Description
AnExtremeValueDistribution
object consists of parameters, a model description, and sample data for an extreme value probability distribution.
The extreme value distribution is appropriate for modeling the smallest value from a distribution whose tails decay exponentially fast, for example, the normal distribution. It can also model the largest value from a distribution, such as the normal or exponential distributions, by using the negative of the original values.
The extreme value distribution uses the following parameters.
