The Skew Normal Distribution

Description

Density for the skew normal distribution with location xi, scale omega, and shape alpha.

Usage

dsnorm(x, xi, omega, alpha, logC = 0, log = FALSE)

Arguments

x	Vector of quantiles.
xi	Location parameter.
omega	Scale parameter.
alpha	Shape parameter.
logC	Log-normalization constant.
log	Logical; if TRUE, returns the log density.

Value

A numeric vector of (log) density values.
