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.
