This function applies a user-supplied performance metric to a prediction result object.
Usage
custom_performance(x, custom_fun, split_list = NULL)
Arguments
- x
The prediction result object.
- custom_fun
The function used to compute performance metrics, i.e., custom_fun(x).
- split_list
An optional named list of splitting groups. If provided, the performance metric will be computed for each group and returned as a named vector.
Value
A named vector with the calculated custom performance metric(s).
Details
The function allows users to apply a custom performance metric to a prediction result object.
If a split list is provided, the performance metric will be computed for each group separately, and the results will be returned as a named vector.
