GenExtremeValue

The Generalized Extreme Value Distribution

Description

Density, distribution function, and random generation for the generalized extreme value distribution with location mu, scale sigma and shape xi.

Usage

dgen_extreme_value(x, mu = 0, sigma = 1, xi = 0, log = FALSE)

pgen_extreme_value(
  q,
  mu = 0,
  sigma = 1,
  xi = 0,
  lower.tail = TRUE,
  log.p = FALSE
)

rgen_extreme_value(n, mu = 0, sigma = 1, xi = 0)

Arguments

`x, q`	Vector of quantiles.
`mu`	Vector of locations.
`sigma`	Vector of scales.
`xi`	Vector of shapes.
`log`	Logical; If `TRUE`, values are returned on the log scale.
`lower.tail`	Logical; If `TRUE` (default), return P(X <= x). Else, return P(X > x) .
`log.p`	Logical; If `TRUE`, values are returned on the log scale.
`n`	Number of samples to draw from the distribution.

Details

See vignette("brms_families") for details on the parameterization.
