Manages Training and Test Data for building Statistical Models and provides functionality for Crossvalidation. Manages data together with surrogate information. The surrogate variables are provided through a vector (see DataManager), and can contain both continuous or categorical data. The surrogate data is provided through files. One file for each dataset, and one file describing the types of surrogates. This file is also an ascii file with space or EOL separated values. Those values are either 0 or 1, standing for respectively categorical or continuous variable. This class does not support any missing data, so each dataset must come with a surrogate data file, all of which must contain the same number of entries as the type-file. More...

Manages Training and Test Data for building Statistical Models and provides functionality for Crossvalidation. Manages data together with surrogate information. The surrogate variables are provided through a vector (see DataManager), and can contain both continuous or categorical data. The surrogate data is provided through files. One file for each dataset, and one file describing the types of surrogates. This file is also an ascii file with space or EOL separated values. Those values are either 0 or 1, standing for respectively categorical or continuous variable. This class does not support any missing data, so each dataset must come with a surrogate data file, all of which must contain the same number of entries as the type-file.
