\description{
\itemize{
\item{\strong{test.mean}}{\cr Mean of performance values on test sets.}
\item{\strong{test.sd}}{\cr Standard deviation of performance values on test sets.}
\item{\strong{test.median}}{\cr Median of performance values on test sets.}
\item{\strong{test.min}}{\cr Minimum of performance values on test sets.}
\item{\strong{test.max}}{\cr Maximum of performance values on test sets.}
\item{\strong{test.sum}}{\cr Sum of performance values on test sets.}
\item{\strong{train.mean}}{\cr Mean of performance values on training sets.}
\item{\strong{train.sd}}{\cr Standard deviation of performance values on training sets.}
\item{\strong{train.median}}{\cr Median of performance values on training sets.}
\item{\strong{train.min}}{\cr Minimum of performance values on training sets.}
\item{\strong{train.max}}{\cr Maximum of performance values on training sets.}
\item{\strong{train.sum}}{\cr Sum of performance values on training sets.}
\item{\strong{b632}}{\cr Aggregation for B632 bootstrap.}
\item{\strong{b632plus}}{\cr Aggregation for B632+ bootstrap.}
\item{\strong{testgroup.mean}}{\cr Performance values on test sets are grouped according
to resampling method. The mean for every group is calculated, then the mean of those means.
Mainly used for repeated CV.}
\item{\strong{testgroup.sd}}{\cr Similar to \strong{testgroup.mean} - after
the mean for every group is calculated, the standard deviation of those means is obtained.
Mainly used for repeated CV.}
\item{\strong{test.join}}{\cr Performance measure on joined test sets.
This is especially useful for small sample sizes where unbalanced group sizes have a significant impact
on the aggregation, especially for cross-validation test.join might make sense now.
For the repeated CV, the performance is calculated on each repetition and then aggregated
with the arithmetic mean.}
