Summary of resampled performance estimates
This function uses the out-of-bag predictions to calculate overall performance metrics and returns the observed and predicted data.
resampleSummary(obs, resampled, index = NULL, keepData = TRUE)
- A vector (numeric or factor) of the outcome data
- For bootstrapping, this is either a matrix (for numeric outcomes) or a data frame (for factors). For cross-validation, a vector is produced.
- The list to index of samples in each cross--validation fold (only used for cross-validation).
- A logical for returning the observed and predicted data.
The mean and standard deviation of the values produced by
postResample are calculated.
- A list with:
metrics A vector of values describing the bootstrap distribution. data A data frame or
NULL. Columns include
group(for tracking cross-validation folds or bootstrap samples)
resampleSummary(rnorm(10), matrix(rnorm(50), ncol = 5))
