Function to apply Approximate Cumulative Distribution (ACD)

Description

Applies the acd transformation as outlined in Royston (2014) and Royston and Sauerbrei (2016). Designed to work with the output of fit_acd(), Please refer to the corresponding documentation for more details.

Usage

apply_acd(x, beta0, beta1, power, shift, scale, ...)

Arguments

x	a numeric vector.
beta0, beta1	each a numeric value, representing the coefficients of the FP1 model for the ACD transformation.
power	a numeric value, estimated power to be used in the FP1 model for the ACD transformation.
shift	a numeric value that is used to shift the values of x to positive values.
scale	a numeric value used to scale x.
...	not used.

Value

The transformed input vector x.
