Inverse Box-Cox transformation — g_inv

Evaluate the inverse Box-Cox transformation. Negative values are permitted.

Usage

g_inv_bc(s, lambda)

Arguments

s: argument(s) at which to evaluate the function
lambda: Box-Cox parameter

Value

The evaluation(s) of the inverse Box-Cox function at the given input(s) s.

Note

Special cases include the identity transformation (lambda = 1), the square-root transformation (lambda = 1/2), and the log transformation (lambda = 0).

#' @examples # (Inverse) log-transformation: g_inv_bc(1:5, lambda = 0); exp(1:5)

# (Inverse) square-root transformation: note the shift and scaling g_inv_bc(1:5, lambda = 1/2); (1:5)^2
