Description
|
|
•
|
The Gumbel distribution is a continuous probability distribution with probability density function given by:
|
|
subject to the following conditions:
|
•
|
The Gumbel distribution is also known as the type I extreme value distribution.
|
•
|
The Gumbel variate with location parameter a and scale parameter b is related to the Exponential variate with scale parameter b according to the formula: Gumbel(a,b) ~ a - log(Exponential(b))
|
•
|
Note that the Gumbel command is inert and should be used in combination with the RandomVariable command.
