Skew Normal Log-Likelihood

Skew Normal Log-Likelihood

Usage

log_lik_skewnorm(
  x,
  location = 0,
  scale = 1,
  shape = 0,
  tlower = -Inf,
  tupper = Inf,
  ...,
  mean,
  sd
)

Arguments

x

A numeric vector of values.

location

A numeric vector of the location parameter.

scale

A non-negative numeric vector of the scale parameter.

shape

A numeric vector of shape. Negative values result in leftward skew, while positive values result in rightward skew.

tlower

A numeric vector of the lower truncation point.

tupper

A numeric vector of the upper truncation point.

...

Unused.

mean

A numeric vector of the location parameter. Described as "a numeric vector of the means" prior to to v. 0.10.1. Will be removed in a future version.

sd

A non-negative numeric vector of the scale parameter. Described as "a non-negative numeric vector of the standard deviations" prior to v. 0.10.1. Will be removed in a future version.

Value

An numeric vector of the corresponding log-likelihoods.
