Relative root mean squared error

rrmse.Rd

Calculate the relative root mean squared error. `rrmse()` expresses the RMSE as a proportion of either the **mean** or **range** of the true values.

Usage

rrmse(data, ...)

# S3 method for class 'data.frame'
rrmse(
  data,
  truth,
  estimate,
  na_rm = TRUE,
  case_weights = NULL,
  normalization = "mean",
  ...
)

rrmse_vec(
  truth,
  estimate,
  na_rm = TRUE,
  case_weights = NULL,
  normalization = "mean",
  ...
)

Arguments

data

A `data.frame` containing the columns specified by the `truth` and `estimate` arguments.

...

Additional arguments passed to lower-level functions.

truth

The column identifier for the true results (numeric).

estimate

The column identifier for the predicted results (numeric).

na_rm

A `logical` value indicating whether `NA` values should be removed.

case_weights

Currently not implemented.

normalization

Character string specifying the normalization method: `"mean"` (default) or `"range"`.
