# AND: Quantile-based asymmetric normal distribution In QBAsyDist: Asymmetric Distributions and Quantile Estimation

## Description

Density, cumulative distribution function, quantile function and random sample generation from the quantile-based asymmetric normal distribution (AND) introduced in Gijbels et al. (2019a).

## Usage

 ```1 2 3 4 5 6 7``` ```dAND(y, mu, phi, alpha) pAND(q, mu, phi, alpha) qAND(beta, mu, phi, alpha) rAND(n, mu, phi, alpha) ```

## Arguments

 `y, q` These are each a vector of quantiles. `mu` This is the location parameter μ. `phi` This is the scale parameter φ. `alpha` This is the index parameter α. `beta` This is a vector of probabilities. `n` This is the number of observations, which must be a positive integer that has length 1.

## Value

`dAND` provides the density, `pAND` provides the cumulative distribution function, `qAND` provides the quantile function, and `rAND` generates a random sample from the quantile-based asymmetric normal distribution.
