Skew-Lognormal Deviances

Skew-Lognormal Deviances

Usage

dev_skewlnorm(
  x,
  locationlog = 0,
  scalelog = 1,
  shapelog = 0,
  res = FALSE,
  ...,
  meanlog,
  sdlog,
  shape
)

Arguments

x

A numeric vector of values.

locationlog

A numeric vector of location parameters of log(x).

scalelog

A non-negative numeric vector of scale parameters of log(x).

shapelog

A numeric vector of shape parameters of log(x). Negative values result in leftward skew, while positive values result in rightward skew.

res

A flag specifying whether to return the deviance residual as opposed to the deviance.

...

Other arguments passed to methods.

meanlog

A numeric vector of the means on the log scale.

sdlog

A non-negative numeric vector of the standard deviations on the log scale.

shape

A non-negative numeric vector of shape.

Value

An numeric vector of the corresponding deviances or deviance residuals.
