Detailed Description

The Largest Extreme Value distribution Random Number Generator (RNG).

This class supports the creation of objects that return random numbers from a fixed Largest Extreme Value distribution. This corresponds to the type-I Generalized Extreme Value distribution, also known as Gumbel distribution (https://en.wikipedia.org/wiki/Gumbel_distribution).

The probability density function of a Largest Extreme Value variable is defined as:

\[
     P(x; \mu, \beta) dx = \frac{1}{\beta} e^{-(z+ e^{-z})} dx, \quad z = \frac{x - \mu}{\beta}
  \]

where $\mu$ is the Location configurable attribute and $\beta$ is the Scale configurable attribute.

The Largest Extreme Value RNG value $x$ is generated by

\[
     x = \mu - \beta \log(-\log(u))
  \]

where $u$ is a uniform random variable on [0,1).

The mean of the distribution is:

\[
     E = \mu + y \beta
  \]

where $y$ is the Euler-Mascheroni constant.

The variance of the distribution is

\[
     \sigma^2 = 6 \pi^2 \beta^2
  \]
