alcdf {bqror}R Documentation

cdf of an asymmetric Laplace distribution

Description

This function computes the cumulative distribution function (cdf) of an asymmetric Laplace (AL) distribution.

Usage

alcdf(x, mu, sigma, p)

Arguments

x

scalar value.

mu

location parameter of an AL distribution.

sigma

scale parameter of an AL distribution.

p

quantile or skewness parameter, p in (0,1).

Details

Computes the cdf of an AL distribution.

CDF(x) = F(x) = P(X \le x)

where X is a random variable that follows AL(\mu, \sigma, p)

Value

Returns the cumulative probability value at point '"x"'.
