\if{html}{\out{<div class="arguments">}}
\describe{
\item{\code{CV}}{List describing cross-validation to run. Slots:
- type: 'vfold' or 'MC' for Monte-Carlo (default: MC)
- V: number of runs (default: 10)

  (irrelevant for V-fold). Default: 0.2.
- shuffle: wether or not to shuffle data before V-fold.
  Irrelevant for Monte-Carlo; default: TRUE}
