# PowerLaplace: The Power Laplace Distribution In powdist: Power and Reversal Power Distributions

## Description

Density, distribution function, quantile function and random generation for the power Laplace distribution with parameters mu, sigma and lambda.

## Usage

 ```1 2 3 4 5 6 7 8 9``` ```dplaplace(x, lambda = 1, mu = 0, sigma = 1, log = FALSE) pplaplace(q, lambda = 1, mu = 0, sigma = 1, lower.tail = TRUE, log.p = FALSE) qplaplace(p, lambda = 1, mu = 0, sigma = 1, lower.tail = TRUE, log.p = FALSE) rplaplace(n, lambda = 1, mu = 0, sigma = 1) ```

## Arguments

 `x, q` vector of quantiles. `lambda` shape parameter. `mu, sigma` location and scale parameters. `log, log.p` logical; if TRUE, probabilities p are given as log(p). `lower.tail` logical; if TRUE (default), probabilities are P[X ≤ x ], otherwise, P[X > x]. `p` vector of probabilities. `n` number of observations.

## Details

The power Laplace distribution has density

b, where -∞<μ<∞ is the location paramether, σ^2>0 the scale parameter and λ>0 the shape parameter.

## Examples

 ```1 2 3 4``` ```dplaplace(1, 1, 3, 4) pplaplace(1, 1, 3, 4) qplaplace(0.2, 1, 3, 4) rplaplace(5, 2, 3, 4) ```
