%description
The fast cross-validation via sequential testing (CVST) procedure is an
improved cross-validation procedure which uses non-parametric testing
coupled with sequential analysis to determine the best parameter set on
linearly increasing subsets of the data. By eliminating under-performing
candidates quickly and keeping promising candidates as long as possible,
the method speeds up the computation while preserving the capability of a
full cross-validation. Additionally to the CVST the package contains an
implementation of the ordinary k-fold cross-validation with a flexible and
powerful set of helper objects and methods to handle the overall model
selection process. The implementations of the Cochran's Q test with
permutations and the sequential testing framework of Wald are generic and
can therefore also be used in other contexts.
