skew_normal_distribution: Skew Normal Distribution Functions

Description

Functions to compute the probability density function, cumulative distribution function, and quantile function for the Skew Normal distribution.

Usage

skew_normal_pdf(x, location = 0, scale = 1, shape = 0)
skew_normal_lpdf(x, location = 0, scale = 1, shape = 0)
skew_normal_cdf(x, location = 0, scale = 1, shape = 0)
skew_normal_lcdf(x, location = 0, scale = 1, shape = 0)
skew_normal_quantile(p, location = 0, scale = 1, shape = 0)

Value

A single numeric value with the computed probability density, log-probability density, cumulative distribution, log-cumulative distribution, or quantile depending on the function called.

Arguments

x

quantile

location

location parameter (default is 0)

scale

scale parameter (default is 1)

shape

shape parameter (default is 0)

p

probability (0 <= p <= 1)
