alcdfstd: cdf of a standard asymmetric Laplace distribution

In bqror: Bayesian Quantile Regression for Ordinal Models

cdf of a standard asymmetric Laplace distribution

Description

This function computes the cdf of a standard AL distribution i.e. AL(0, 1 ,p).

Usage

alcdfstd(x, p)

Arguments

x	scalar value.
p	quantile level or skewness parameter, p in (0,1).

Details

Computes the cdf of a standard AL distribution.

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

where X is a random variable that follows AL(0, 1 ,p).

Value

Returns the cumulative probability value at point x for a standard AL distribution.
