Description

Invert a log transformation

Usage

## S3 method for class 'step_log'
invert(object, predictions, ...)

Arguments

object	A recipe after fitting a model
predictions	A data frame with .pred
...	Other arguments

Value

A tibble with the log transformation inverted for .pred

Examples

data <- tibble::tibble(
  y = rlnorm(n = 1000, meanlog = 0, sdlog = 1),
  x = rnorm(n = 1000)
)

adj <- recipes::recipe(y ~ x, data = data) |>
  recipes::step_log(recipes::all_outcomes()) |>
  recipes::prep()
  
invert(
  object = adj$steps[[1]], 
  predictions = tibble::tibble(.pred = adj[["template"]][["y"]])
