tronco.kfold.prederr {TRONCO} | R Documentation

## tronco.kfold.prederr

### Description

Perform a k-fold cross-validation using the function bn.cv and scan every node to estimate its prediction error. For details and examples regarding the statistical assesment of an inferred model, we refer to the Vignette Section 7.

### Usage

    tronco.kfold.prederr(
      x,
      models = names(as.models(x)),
      events = as.events(x),
      runs = 10,
      k = 10,
      cores.ratio = 1,
      silent = FALSE
    )

### Arguments

`x` | A reconstructed model (the output of tronco.capri)
`models` | The names of the selected regularizers (bic, aic or caprese)
`events` | a list of event
`runs` | a positive integer number, the number of times cross-validation will be run
`k` | a positive integer number, the number of groups into which the data will be split
`cores.ratio` | Percentage of cores to use. coresRate * (numCores - 1)
`silent` | A parameter to disable/enable verbose messages.

### Examples

    data(test_model)
    tronco.kfold.prederr(test_model, k = 2, runs = 2, cores.ratio = 0)
