Adjust Skew Normal Distribution Parameters for Sensitivity Analyses

Expands (scale_mult > 1) or reduces (scale_mult < 1) the scale parameter of the Skew Normal distribution without changing the mean.

Usage

sens_skewnorm(location, scale, shape, scale_mult = 2, ..., mean, sd, sd_mult)

Arguments

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.

scale_mult

A non-negative multiplier on the scale of the distribution.

...

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.

sd_mult

A non-negative multiplier on the scale of the distribution.

Value

A named list of the adjusted distribution's parameters.
