R: The Asymmetric Laplace Distribution

AsymLaplace {brms} | R Documentation

## 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 samples to draw from the distribution.

### Details

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