##### "Reverse" Gumbel Distribution Functions

Density, distribution function, quantile function and random generation for the “Reverse” Gumbel distribution with parameters location and scale.

Keywords
distribution
##### Usage
dRevGumbel (x, location = 0, scale = 1)
pRevGumbel (q, location = 0, scale = 1)
qRevGumbel (p, location = 0, scale = 1)
rRevGumbel (n, location = 0, scale = 1)
qRevGumbelExp(p)
##### Arguments
x, q
numeric vector of abscissa (or quantile) values at which to evaluate the density or distribution function.
p
numeric vector of probabilities at which to evaluate the quantile function.
location
location of the distribution
scale
scale ($> 0$) of the distribution.
n
number of random variates, i.e., length of resulting vector of rRevGumbel(..).
##### Value

a numeric vector, of the same length as x, q, or p for the first three functions, and of length n for rRevGumbel().

##### See Also
