By eliminating under-performing candidates quickly\nand keeping promising candidates as long as possible, the\nmethod speeds up the computation while preserving the\ncapability of a full cross-validation. Additionally to the CVST\nthe package contains an implementation of the ordinary k-fold\ncross-validation with a flexible and powerful set of helper\nobjects and methods to handle the overall model selection\nprocess. The implementations of the Cochran's Q test with\npermutations and the sequential testing framework of Wald are\ngeneric and can therefore also be used in other contexts.", "License": "GPL (>= 2.0)",
