AsymLaplace: The Asymmetric Laplace Distribution

In paul-buerkner/brms: Bayesian Regression Models using 'Stan'

The Asymmetric Laplace Distribution

Description

Density, distribution function, quantile function and random generation for the asymmetric Laplace distribution with location mu, scale sigma and asymmetry parameter quantile.

Usage

dasym_laplace(x, mu = 0, sigma = 1, quantile = 0.5, log = FALSE)

pasym_laplace(
  q,
  mu = 0,
  sigma = 1,
  quantile = 0.5,
  lower.tail = TRUE,
  log.p = FALSE
)

qasym_laplace(
  p,
  mu = 0,
  sigma = 1,
  quantile = 0.5,
  lower.tail = TRUE,
  log.p = FALSE
)

rasym_laplace(n, mu = 0, sigma = 1, quantile = 0.5)

Arguments

x, q	Vector of quantiles.
mu	Vector of locations.
sigma	Vector of scales.
quantile	Asymmetry parameter corresponding to quantiles in quantile regression (hence the name).
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.
p	Vector of probabilities.
n	Number of draws to sample from the distribution.

Details

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